I did say Infinity 2.0, this is just the natural progression of what they wanted with Infinity. But at least this way, it doesn't bleed over into regular BTB/Team Slayer.
But people are going to naturally complain they can't buy power weapons or vehicles in Arena. I bet Arena will become the new slur against competitive players. You Arena babies and your MLG, we just want to have fun etc.
That seems really dumb, and if it happens it is just stupid forum diarreah.
Really, people will probably just play whatever they like and not give a shit what other people are playing.
