Point is they don't want to quit.
People do leave over things like their sense of community is gone, as what's the point in playing a game that resembles a battleground 24/7?
CRZ came and made it too much of a chore to multibox for me (zone change stuttering that's unplayable). Without that to level multiple toons, it really becomes pointless to play. CRZ ruined leveling 4 toons to 85 in time for MoP, so truly not interested if Blizz isn't interested in keeping betaware off live servers to ruin the fun for players. If that's how customers are treated, it's time for customers to vote with their wallets -- BF3 Premium is looking much better for play value, instead.
