That is a completely separate discussion. Personally, I think the differences should be on the minor side and mostly flavor, because i care more about giving players freedom than making sure x race is better in y class.
Maybe give each race a selection of feats they can choose at lvl 1? Some overlapping with other races, like toughness, some unique to them. Would certainly help in getting away from race x->class y thinking.
Don't you just hate it when people with dumb opinions have nice avatars?
