To be honest, I can't say I noticed an awful lot of bugs so far, so I don't see why the comic should stress this aspect so much. In fact, almost none, save for graphical glitches and invisible walls, though I know others did.
Plenty of other problems, of course, especially with the abundance of pointless repetitive quests disguised with cutscenes, among which it is quite hard to find the sparse worthwhile ones. Conceptual conflicts with my view of a proper MMORPG are many, but they were known from the start; the game being positioned as WoW/KotOR.
Perhaps they will expand on the more enjoyable aspects. Inserts quests with proper choices, expand dialogue options beyond 3, insert more notes on lore, make the world more interactive, add optional planets, attach some form of multiplayer for the space arcade, add other mini-games, etc. If they choke it full of content, it will be a decent theme park, and diversity of content was part of what made UO good (while its lack made WoW shallow).
But bugs? Say, Darkfall was one huge bug at release, but SWTOR seems perfectly normal for an MMO in this regard.
