I am absolutely doing my best to understand the objections you are raising, but maybe we just have such a radically different view of the game. From where I'm sitting, multiclassing is already weak in most cases, and pure is in no danger of being outclassed, for most classes. You seem to view it otherwise.
I've been talking facts this whole thread. The facts that the devs have provided us with.We'll talk facts when more data comes out.
