we're looking for a great PvP game, something which AoC have made great claims that they can deliver, and I dont mean 6 months after release.
Well if you want it perfect dont pick it up on the day of release, pick it up in 6 months or when its been reviewed properly.
The only mmo that I can recall having few bugs on release was LOTRO.
If its a pvp mmo you can be guaranteed there will be tons of bugs.
