Would also like to see a PC port as well as cross-platform play. Especially with next gen coming out, not all my friends buy the same console and it would be nice to play with all of them together. Would also allow PS players to play against Xbox players and vice versa.
For World of Chel specifically, I'd like to see my character actually progress and get better, putting points into stats that make him better and don't take away from other traits (similar to how FIFA handles their Pro Clubs). Also revising the playoff format. Some mix of how it used to be and how it is now. I like the ranking system, but I am only a gold or platinum playing against elites in Div 1 and can't get consistent enough to actually rank up because we always play such good opponents.
