B. There will be more classes and maybe even races. "If not all at once they could example release 1-2 classes every second month until all classes are released that will bee in the game." I do NOT know this. I hope we get more classes in Early Access ,but I know that there will be more classes in this game.
Honestly i hope they choose "all at once, as soon as possible approach" ... otherwise there is danger that last class or race will have conciderable less feedback than all the others. :-/
Also i believe that i have heard that EA was suppose to last (At least, and not in total, i hope?) a year ... that seem impossible by now, since we would have almost first half of testing behind us and we werent even able to test everything so far.
