As for the release of elemental evil i don't think there is a date for it yet on xbox one except that it will come "soon" after the PC release. And i think the paladin will be free just like the hunter ranger and scourge warlock :) it would be wierd for them to suddenly put a price on the classes :p
I was a hunter-ranger in closed beta and now aswell in release :) just love classes with bows ^^ and being able to switch to melee as awesome aswell :)
I never understod the point of racing to max level. When you get to 60 there is like nothing to do cuz most of the other players are still leveling. And it totally ruins the fun to rush imo :p
I agree on that a minimaps not needed but it could be a nice addition to ppl that want it. Though their first priority should be to fix the UI layout before they clutter it even more with a mini map. At the moment it really takes up to much space and it should be placed More to the edges of the screen imo.
There won't be a "Open beta" :) The game will go directly to full game launch when the last closed beta ends. Its already out in china (xbox one version) and since its been out for years on PC there is no need for an open beta :)
