Seriously.
My Silvershard was done in one, and I took like 4 games for Kotmogu. I had no problems with it, and I think it's pretty awesome that Blizzard had this as part of the questline.
PvE all-stars are hilarious - "oh my god, Blizzard is making me do another facet of the game?!?"
To be fair, Silvershard is just a bad BG all-around. Kotmogu's fun to understand and fun to play.
