Honestly T2 was probably the most interesting boss mechanically in the 2.0, 3.0, 4.0 series. A boss where you could determine which buffs it would have by the adds and order of room you enter through prior to the final room. Outside of the cheese strat this boss is still conceptually above anything we faced so far. They should just structure raids to be one giant dungeon with each boss being a "checkpoint" upon clearing and you would be able to return to said check point if you leave the instance. Areas in between could be for mobs and lore, via interactive items/npc and even switches you need to activate to gain access to the next boss. It could also make for one hell of a speed run doing 4 savage bosses in one lockout instead of having to re-queue for the next floor.

Currently I would say that "Savage Trials" would be an appropriate term for what we have as anything resembling a "Raid" ended in 3.0. I would give Omega a pass since its all a battle simulation tournament so any sense of dealing with trash, when he could easily put you in the next boss fight, would be redundant. However I think its too late for 5.0, raids to be changed but maybe Yoshi will take this thread to heart and consider it for 6.0. You could still change the title to Savage Trials to better reflect the battle design.
