You're comparing Blizzard to Bioware. That's funny, because for Bioware to be more like Blizzard, it would be an improvement... despite the typicality Blizzard led us to in the past. I guess you could say Bioware shouldn't take as long as Blizzard did to get their act together. But, I'd rather just say they need to learn from Blizzard's mistakes and not have a garbage community relations team from the get go.
I'm not disagreeing with you, however. "Immersion" has become more and more a part of MMO culture. The "novice-role-play" if you will. Even on non-RP servers (in all games) you'll find people slashing emotes and sporting five kinds of aesthetic gear. A role playing server on one of these games is over the top comparably, but the lack of "full on" role players does not negate the fact that MOST players have some kind of immersion need.
After the age of about 13, players start doing more than just "wasting time" in a game. They start getting attached to characters, almost like pets. We grow accustom to our characters or we relate through their egos.. OUR alter-egos.
I'd say we should request they focus less on end game and more on ALL-game. Very few people will raid end game with a character they hate. Dropping a bomb like "you can't wear hoods" at the level you find this info out is a little ridiculous!
To the Devs:
1) Twi'lek have appendages that are NOT fixed. MANY of the Twi'lek have pulled them over their shoulders or tied them back. There is ZERO reason their tails can not fit under the hood.
2) The development team in charge of this change would be a VISUAL team. This team is (typically in all game endeavors) the LEAST worked team after launch.
This said, Bioware, you really have no excuse.
