Probably so, haven't seen the creator of a character ever give them a lame death because...well its their character. I mean would you give a character, that you spent time working on, giving their abilities, stories, villains, companions, etc and at the end give them a lame death?
No I would not. You are correct that an author would not kill their own character in a lame way. But I think the death should be fitting to the character. In my opinion, Revan should have been killed by the Emperor. Drew missed his chance for his character to be killed by the most powerful being in the galaxy. It would have been a good death. Revan's fought countless enemies and defeated them. Shouldn't his death come from a battle that he can't
win? I think so.
