In fact, when DPS doing dungeons, they not always keep their threat lower than tank. Good DPS can go for conscious risk of getting hit. For example by focusing some enemies to save healer when tank didn't manage situation. Some do CC.
Some just attack mobs in ranged combat, some already kite if possible.
In fact "tank" is just name for "party leader" role, who just take responsibility for assembling party for dungeon and running it? Someone to blame in things get bad or someone dies.
Is it possible to run organized group without leader? I don't think so. Even if there is no entitled leader, someone always coordinate actions.
Should the tank be always a party leader? I don't think so.
Good healer take same responsibility and become party leader. Being a leader isn't related to any class.
It turns out that we just caught in tank-healer-dps LFT model because it was copied from TBC/WoTLK. May be LFT should change?
For example, players in LFT should choose between:
- ranged combat
- melee combat
There should also be two buttons: "LFM" and "LFG".
If someone press LFG, he is put to queue and wait for someone to press LFM.
If someone press LFM, he automatically become party leader.
LFT should find:
- 1 character of class Priest, Druid, Shaman with "ranged combat" option.
If leader matches this criteria, search ends. Paladins should be able to choose "ranged combat" to help LFT identify them as healers. - 1 character of class Warrior, Paladin, Druid, Shaman with "melee combat" option. If leader matches this criteria, search ends.
- 1 character of class Mage, Warlock, Hunter with "ranged combat" option.
- more DPS. Preferably of classes not matching the ones who already in party. Preferably to make equal amount of melee/ranged combat characters.
This design of LFT will assume that all warriors and feral druids could potentially be a tank. But they are not forced to be party leaders. There will be some other guy to blame if things get bad.
