The stats have effects beyond the damage boost; elves do in effect have a better dodge chance because of the +2 finesse, which makes it reasonably useful regardless of the character's combat style. Likewise, the human +2 Wits adds to crit chance and initiative, which are useful to everyone.
Intelligence and Strength give additional magical/physical armor. This is likewise universally useful, although they amount that they add probably isn't as helpful with the current numbers. Lizards also get a boost to their breath weapon from Int, so there is that.
