I beg to differ. The new system covers the following problems (some of them are related to synergies):
- presence of synergies added to system complexity,
- new skills had to contain class information and new synergies,
- through minmaxing one was able to skyrocket with skill total,
- when introducing playing in a radically different setting, designers had to worry about how the systems affect classes and synergies,
- no cross-class/class skills means one complicated table less,
- no cross-class/class skills allows for easier class descriptions and more varied skill builds for characters.
Of course, I am not familiar with latest version of skill system, but I'd like to say that I really liked its simplicity.
