"Classes" in City of... are not any where near as straight jacketed as you might think. In fact, there are plenty function cross over. Blasters can be melee, ranged or both. Defenders and Scrappers can tank, etc. Hell, Scrappers can mez as well (spells to you Elf/Dwarf lovers) And Villains has some fairly strange and unusual generalist combinations compared to stuff like LOTR, EQ, etc.
Skill point based is better than class based. Neither Conan (from what I've heard) nor City of is skill point based, but I give City a pass because it tries to flex the class functions somewhat.
Conan might do ok with class based but that remains to be seen. Just like every other feature of the game remains to be seen. Still not going to get excited by maybe and wishful thinking.
