It is kind of how progression goes in an MMO. Get powerful enough to zerg said boss and ignore everything else.

My experience from XI - Kirin, Dynamis Lord etc. Kraken Club + DRK or MNK = Dead Boss. XP PTs went from Arrow Burn to Axe Burn to just TP Burn. Tanks BSTs and Casters got left out. But yet they continued to level and find a way to survive.

Let people play their own way and stop crying.
