As exciting as these changes sound on paper, I'm more excited about the prospect of optimization and refinement of elements that already exist in the game. A bigger and deeper endgame is going to be great, but after this massive patch comes through, I hope that the next few patches consist of the following refinement tasks:
-balancing/improving perks
-balancing/improving grenade options (IE, nerf LURES and buff/change prox. mines)
-buffing Gunner / nerfing Driller
-enhancing class balance in general by adding more positive intersection effects between classes
There'll be time for some polish and optimization too, don't worry. :D
