I'm not quite sure how to answer the question. I do want to be able to define my character prior to play, I don't necessarily think the restrictive leveling in past systems made any sense. So do I want "classes"? Yeah, sort of. but the way they've been implemented in the past left a lot to be desired.
Yeah, that's what they were.
Now the main reason their existence is removed (M&m), why keep them?
To quickly comment on this: Removing a critical part of particular system and then saying, "Hey, without this part, the system doesn't really work. We should cut the system," is pretty absurd. The only reason the system no longer works is because you cut that part out of it.
It's like in Deus Ex: Human Revolution. They inserted this weird take-down ability that takes out your opponent in a single shot automatically every time. Then they said, "Oh [censored], this is way overpowered. We better limit it by requiring take downs to use bio-energy." They broke the system, and rather than fixing it by properly implementing melee combat, they simply further [censored] up the system they broke.
