Bethesda said there won't be any classes to choose from, instead you are free to skill whatever skills you want your character to have.
But what if you still get a class name depending on the combination of skills you've chosen.
I was thinking about something similar as in http://www.titancalc.com/.
This would be solely cosmetic. Your class name won't restrict nor unlock skills.
It just gives your something to identify your character's "class" and make it easier to share builds with other players.
