Basically it would make humans obsolete for everything but dex builds, and would make for an especially insane AP.

There are no real down sides to this race.. the dex and wis is still high compared to other str-based races. The con is pretty average (lower than giants, but about middle of the road overall). So.. it's basically all upside, no "bad" stats that you have to compensate for (below 18 wis races only get 2 pracs per lvl, below 17 int races have to spend 3 pracs to get to 75%, for example)

By comparison, look at a minotaur (which is kinda what you're going for.. only with high wis instead of int)
Max Stats: 23str, 16int, 22wis, 19dex, 21con, 11chr

They're already a very strong race statwise, but that's alleviated by how rare they are. PLUS they have very low int (and charisma.. cause that matters). Considering int is a bigger factor for most (all?) classes than wis, you'll need to have a downside at least equal to a mino's if not worse, to be balanced.
