if pala / shama is equal to Rogue / Warrior then why bring rogue / warrior when pala / shama also have utility and healing.
The problem is raid design, not the classes.
look at how many builds are practical for Leveling, Dungeons and PVP, then contrast to raids… The issuse is raid designs are trash and always have been.
So the real solution is change how raids are designed instead of making all the classes do the same things equally.
The net output of the adventure that is class balancing for raid = Retail, so may as well just go play retail at that point instead because it has a bigger budget and 100X the content.
