You are welcome.
I am glad you are enjoying it, it is indeed very addictive.
It is a shame that Mace is so crap, since he was probably one of the most bad-ass Jedi. Unfortunately he really doesn't do anything for the game. He supposedly a Tank, but has no taunt ability and his actual active abilities are just rubbish. If I see an enemy team with Mace, he invariably gets left until last as he is no real threat. At least Chewie (who is pretty rubbish as well) has a taunt and heal ability. He may hit like a wet fish, but he has a use (to soak up blasts and divert attention). I suppose the one use you may have for Mace at this point is he can remove buffs (like taunt) on an enemy, which is useful. Thing is, other characters have similar abilities and bring much more to the table as well. Qui-Gon has the same ability, but other awesome stuff to boot - and characters like Boba Fett ignore taunts altogether.
As you play more and meet the different characters in the arena and Galactic Wars, you will find you tend to have a list of characters that you can safely ignore until last, just as you have a list of enemies that you gotta take down quick or they will wreck you.
