In WKC it didn't make it absolute to do reincarnations to get to do things. You could do pretty much anything given you were properly leveled and geared. Although It could be changed to better suit this world, it wasn't a requirement in that game. Doesn't have to be in this one either. Then again, you will get the people who demand you have exact points in exact stats and that sort of stuff. I do respect your opinion though.
