My preference is Bioware delayed the game for a month or so and ironed out these bugs. MMORPGs usually only get one shot to hook players in, and the first impressions of endgame are not hooking many people in.
It would've taken half a year to fix this wreck they've launched with. Perhaps longer. They released it because it was Christmas, and at Christmas people are vulnerable to expensive **** that doesn't work. Endgame raiding is just so incomplete - there's no point discussing it or taking it seriously because of the amount of issues there are. It's pretty simple to understand this game misses out on fundamental, basic functions that are integral to good MMO gameplay.
