Didn't they say they would cap us to lv10, though?
That only strengthens my point, as each hybrid class will only get 3 total ASIs = not enough to realistically increase Int to 20 without unduly sacrificing Str/Dex.
Larian originally said the cap was level 10, but have since said it will probably be higher. Unclear what they mean by that; 12 is my guess.
