I can sympathize with the not liking of gambits character, I wrote a fanfic not long after x3 came out and I had him in it but didn't use him alot, used his character some in new orleans and a little at the school but I am not real fond of the character either, the thing that would have gotten me the most complaints was the way I used quicksilver and scarlet witchs mother, had her leading a faction of the brotherhood that had separated from magnetos group, and mystique tried hooking up with them, and their mother is who rogue got her abilities for flight and strength from, had mystique trick rogue into stealing her abilities so she could take over the brotherhood in the mothers disguise. Thats where gambit came into play in mine also he started out working for that group of the brotherhood.
