Short Tactics for quick overview, more to come once were there:
Alizabal
2 tanks, melee behind boss, range stacked
boss does 3 abilities:
Seething hate - random player, 200.000 dmg, split, because of that - camps - melee or tanks need also run to group if they get it
Skewer - on tank, does all 2 secs 10.000 dmg, and also 150% more dmg, other tank taunt as soon one has skewer
If 1 tank has skewer, and other has seething hate, then the hate tank taunts, and runs then to group, boss dont do aoe stuff
Last one dont know english name, Knifedance - run away, boss is also immune to dmg
