Classes or classless - I don't mind as long as it works well, is well balanced and every skill has a reason to be there. And if you absolutely NEED a skill (Lockpick in Div 1 for example) you can get it in any class.
That said, I liked the Div 1 system a lot. Just needed the power of traps to be dropped (By about a factor of ten or so) and it would be pretty near perfect, if memory serves.
