I only voted for Coming Soon because it's really bland and boring. Everything else is okay, really.
Seriously, it's one of the most boring stages in any fighting game. It has no music, it's not dynamic, it's plain orange and it seriously lacks any character (pretty much the equivalent of the KOF13 white stage). I would've much preferred if the stage was on a giant motherboard where you could knock opponents around and cause on-screen bugs and anomalies to appear. You know, fun.
I won't disagree that it has it's own dimensions, but come on, just look at it...
Sweat and and DOA are okay, though I would argue that DOA's massive size actually makes tag juggle extenders look more like infinity combos (couple of people watching the stream with me asked me white there are infinites in the game. Had to spend half and hour arguing with them about this), but there really is no necessity to ban any stage. I'm just singling out Coming Soon because it's just shite.
