After comparing d20 to other target number based games (Ars Magica, Dragonlance/Marvel Saga, and Cyberpunk 2020), I've realized that the DCs for D&D are too low by about half as much. I thought about changing all the DCs but that would be too much work. The solution I came up with is to make max ranks equal to 1 + 1/2 per level (round down) and doing a Pathfinder-like solution where I give a +4 bonus to all class skills. Its a bit like 4e/SWSaga, but it also solves the problem of breadth of skill which 3.xe characters lack because at odd levels they will have to spread out their skill points. I would just keep skill focus and the skill enchancer feats as is.
