I wish they had gone with no classes at all. Or maybe just choose a class that gives you +15% XP bonus to certain skills.

Instead of having separate classes with skill lines such as "Ardent Flame", "Assassination", "Stormcalling", etc. I wish there were no classes, and an equal number(or perhaps more) of skill lines could be added such as "One-Handed", "Conjuration", "Alteration", "Illusion", "Acrobatics", etc. Basically, you can use all the classic TES skills and make them fit into this game easily the same way the current skill trees do.

To me, that would be a really cool. And I think the potential for creativity with character/class building would be much higher.
