Replace the original talents file in /Marvel: Ultimate Alliance/Data/Talents.
Has this been included in the v1.1 download? Because the "Health per Kill" is still at +0 at every rank (I downloaded from the v1.1 link in the character mod catalogue a week ago).
P.S. Sorry for the 1 month necro, but I guess it isn't as bad as some of the others in this thread :-D
EDIT: Don't worry guys, I worked out how to fix it myself. I feel clever -.-
One thing I have noticed though (not a bug/issue, just an observation) is that with War Machine, his gatling gun and repulsor rays both shoot rapid fire, with (at the present levels) the repulsor rays doing quite a bit more damage. I'm just wondering, which of these do you guys use most often and why?
