From Penny Arcade, about the problems of PvE endgame grind (in WoW):

Of course I have a bunch of ideas for what I’d like to see Blizzard do to fix this but honestly none of them matter. There are a million other back seat MMO designers bitching at them in their forums every day. What it boils down to is that I trust them. I trust that the game I love will continue to get better and better with each new patch.

You are gullible.
