Thanks for the feedback, Fenix.
I wouldn't say the combat is too easy, though I might need to look at the late game scaling of the psi abilities. Some of them might be too powerful now and with the coming feat changes they will only get stronger.
It's probably a matter of you playing the game better than the average dude, so I might need to add "hard" difficulty for people like you.

Psi boosters are not meant to be rare, just a resource you must manage, like ammo. Concerning the "more psi boosters in early areas" change it practically means there will be a couple psi boosters as static loot in the SGS outpost areas to help psi characters get rolling.
I might add oddity list at some point, it has been suggested a number of times now.
I don't agree that player receives too many skill points. If you max out each skill you take you can only take 8 out of 22 skills which I think is ok. You have enough to make a versatile character, but you're far from being able to take everything.
World map is something that has been discussed many times. The answer currently is a strong maybe.
