Allowing players to choose which servers they connect to for Infinite multiplayer must be in from day one.
Currently in MCC it is almost impossible to get a 8v8 BTB game on any European servers and I lay the blame at the door of 343i. For too long have they ignored the non US communities, yes I understand that their biggest player base is in the US, but if they want to keep and grow the communities out side of America then they must treat them with the respect they deserve.
