Did you know they changed the roster slot purchase for new players?
A friend of mine recently got his co-worker to start playing MPQ. He got into it and when he finally earned another character he was unable to simply buy ONE roster slot. They forced him to purchase THREE. Not a big deal as Hero Coins are plentiful at the beginning of the game. He continued on, built his characters some more and won more rewards and figured by now he would be able to purchase a single roster slot.
Nope. He was once again forced to purchase a 3 pack of roster slots or none. Needless to say he has not bought them yet. I have a hard time seeing this as anything else than D3 trying to force new players to purchase Hero Coins this early on in the game.
I really hate to come on here and post mostly negative things about the developers but they really give little reason not to with all these recent changes
