I'd like to see a soft enrage timer boss at 10% hp start to get a dmg up buff, tanking accessories actually meaning something rather than "oh good...fending...yay...". A boss where we the raid, uses Gobtanks to take off the limbs of a giant boss (gobtanks that tank, heal, dps) then after the limbs are down the fight begins. Something fun, dynamic, that'll make you go "man that was really fun!" a fight where NPCs are actually there and giving us some sort of aid.
