a question about the BP boss battle

[theblastmage]

hey guys, i've heard around the forum people mentioning that they had to make new characters to do the boss fight again, so i was wondering if you were able to do the boss fight more than once.

also, i've done the boss once on my character with another group, but i'm far from completing the quest. i want to know if i'll still be allowed to do the boss fight again once i finish the quest (it's a waist to do all that work for nothing but a lil' extra rep after all)
