Combat Roles

Originally fully developed as an MMO concept, Combat Roles are a somewhat useful concept in designing individual combat systems. These roles have been imported into Tabletop games over the years, most notably by Dungeons & Dragons 4e.

In MMOs

The original trinity was:

• Tank. The guy who goes up front, and absorbs all the damage from the monsters.
• Healer. The guy who makes sure the Tank and Damage stay in combat, rather than dying or needing to retreat.
• Damage. The guy who actually kills the monsters. Usually comes in two varieties, Burst, who does a lot of damage all at once, but is usually fairly slow about it, and DPS ("damage per second") who focuses on doing damage at quick bursts, and DoT, "damage over time", spells and abilities which inflict status effects that do damage continuously.

There are a plethora of side roles, usually one of the above with a little bit below, or two or more of the below:

• The Area of Effect (AoE) guy, who focuses on large groups and areas, as opposed to a Single Target specialist. More a modifier for the trinity; both have value, as sometimes you're fighting a horde (and so the multiplicative effect of AoE is useful), and sometimes you're fighting a singular big monster (and thus, the multiplicative bonus of AoE is lost)
• The Off Tank, who could fill in for the Tank for a short while so he could heal or reposition.
• The Buffer, who boosts his teammates' abilities. May sound useless, but most systems go out of their way to make Buffs valuable. Likely to be combined with Healer, Tank, or Debuffer.
• The Debuffer, who penalizes his enemies' abilities. Similar to the Buffer, but for enemies. Likely to be combined with Tank, Damage (frequently a DoT type), or Buffer.
• The Petmaster, who has a pet or pets, who are either an Off-Tank or extra Damage.
• The Jack of All Trades (or just Jack), who can fill in for more than two of the above, usually at the cost of being good at any one. Usually, has a hard time, as the other classes are more valuable to a group, but as long as they have their own niche, being able to fill in for another in a pinch is still valuable.
• The Crowd Controller, or the Mezzer, who focuses on disabling monsters, particularly large groups, so that their teammates can focus on a few monsters at a time.
• A few games have Area Denial roles (or, more frequently, monsters, especially bosses), who make an area inhospitable to their enemies. Rare, because most MMOs have very weak AI systems, and thus such a role would make AI more complicated than it needs to be.

Aggro

One important concept to understanding the Tank is "Aggro": Monsters target whoever has done the most damage or healing nearby, but Tanks have abilities that either force monsters to attack them, or greatly increase their own Aggro rate without necessarily doing any damage or healing.

Aggro management is quite important in most MMOs, as most Healer and Damage classes are fairly fragile, and an Aggro system gives players a fairly direct and decent risk/reward system, realism be damned.

(See also the DISTRACTION CARNIFEX, which is a case of Real World Aggro management.)

Dungeons and Dragons 4e Roles

Dungeons & Dragons 4e included four explicitly spelled out roles that overlap with the MMO nominclature, so we'll use some of the vocabulary from above.

• The Defender, essentially the Tank, with a small region of Area Denial interrupting anybody who tries to attack anybody but him, since 4e lacked an Aggro system.
  • Class differentiation was usually based on how they stopped monsters from attacking others.
  • Examples from the original PHB: Paladin (for a more Leader-leaning Defender) and Fighter (for a more Striker-leaning Defender)
• The Striker, a Single Target Damage/Debuffer type.
  • Class differentiation within the role was usually based on what kind of damage, how they dealt it, and how close they could get to their opponent.
  • Examples from the original PHB: Rogue, Warlock, Ranger.
• The Leader, a Healer/Buffer, who usually also did Off-Tanking.
  • Class differentiation within the role was usually based on how much of those three the class could be.
  • Examples from the original PHB: Cleric
• The Controller, who did Area of Effect Damage, Area Denial, and Crowd Control-focused Debuffing. The most poorly defined of the four in the initial book.
  • Class differentiation within the role was usually based on very little, as Controllers were all based on "the same as Wizards, but slightly different in some way".
  • Examples from the original PHB: Wizard

Lancer Roles

Lancer includes five roles that apply to both player mech frames and enemy mechs. While enemies are rather clear-cut in their roles, player mechs tend to have roles that can overlap with each other.

• The Artillery is a long-ranged variant of the striker. Because of how prevalent guns are on mechs, mechs in this category usually have ways to guarantee that their shots will make their impact.
  • Frames usually differentiate themselves on what particular weapons they tend to favor and how they manage their ranges.
  • Examples of Artillery Licenses: HA Barbarossa, SSC Monarch
• The Controller usually has the best options for tech attacks of the bunch. This allows them to debuff enemies very quickly, though they could also have some means of area denial that makes moving past them quite difficult.
  • Frames usually differentiate themselves in how they decide to hamper their enemies, either directly or indirectly.
  • Examples of Controller Licenses: SSC Dusk Wing, HORUS Minotaur
• The Defender usually has some means of area denial or protection for others. They also usually have ways to bolster their reactions so that they can more easily halt enemies from attacking their allies.
  • Frames usually differentiate themselves based on how they manage to either shield allies or block enemies.
  • Examples of Defender Licenses: HORUS Gorgon, HA Saladin
• The Striker tends to focus more on up-close warfare, whether or not it involves going into melee. They also tend have options for minor debuffing.
  • Frames usually differentiate themselves on what weapons they favor and how they intend to stay within the ideal range for their weapons.
  • Examples of Striker Licenses: IPS-N Blackbeard, HA Ghengis
• The Support has means to bolster allies, whether it's blocking out negative status effects or augmenting allies.
  • Frames usually differentiate themselves based on how exactly they boost allies
  • Examples of Support Licenses: IPS-N Lancaster, SSC Swallowtail

Outside of 4e

Both the MMO and 4e nomenclature for roles are sometimes used by /tg/, since the terms are somewhat well defined.
