Yes, I am very much disenchanted with the d20 system. I am begining to hate class/level stuff, the extreme importance of the die roll during early levels and the almost irrelevent die roll at high level. d20 really shines during mid-level play (4-9 lvl). Skills matter as magic and magic items haven't overwhelmed them. Combat can be tough, but you can expect to survive many encounters without serious resting. Magic hasn't had time to get out of hand (teleport is one of the worst spells ever for party balance and adventuring).
7th Sea looks like the answer for any game I do decide to run. I really like the way combat is handled very cinamatic, heroes wade through brutes while henchmen and villians provide for tough fights), point based characters instead of level base (which allows you to really reward good role-playing with XP and still have the characters on similar footing), and a truely uniqe magic system. The on sticky point of 7th Sea is the world, the world is very much intwined with the system. Another slight complaint are traits giving more power then ranks in a skill, but this can easily be flipped to allow skill ranks to be kept and trait ranks to provide unkept dice.
After playing 2 years of d20, I have decided that it is no where near the end all be all system (which really worries me because many companies are switching to it).
