Ok so..
1) That would make Humans not the greatest of choices as we will most likely run into far more monster species than human enemies.
2) That could possibly be extremely overpowered considering how many grass surfaces will be in the game and it would also make it completely worthless in any zone without grass.
3) That is a terrible trade off, armor is far too valuable to sacrifice for some damage.
4) They don't really have wings..not that kinda lizard, unless there is a weird species we don't know of, but the current racial ability isn't that great so I guess this one wouldn't be too bad to have considering our current choice.
All in all these don't seem properly thought out, but with tweaking they wouldn't be a bad addition if we could choose between a few racials per race, but they will probably leave them as is and only 1 racial ability per race and at most we will probably see a change of the lizard's dragon breath as it is extremely underwhelming compared to other abilities.
