Heya I'm not on much but figured I'd throw my two cents in. I love making new races as far as the troll goes if you want it to be more balanced I would consider an additional -2 to CHA or perhaps -2 wis If your going for a more warcraft style troll Id just drop Str for Dex and lose a +1 to ac. Seems like when WotC gives a +2 to str they tank two stats.
