I am probbly the only one who thinks this, but i think that reptiles should have a little bit higher max dex, by like 2-4 points.

I disagree.

Reptiles can get 55 wis, int and dex, 60 con and 71 STR. In addition they have water breath and GREAT AC. There is no need for a further boost.

I'd have to agree, reptiles have very good class flexibility and great bonus abilities.
