First off, I’d like to say how happy I am with how this new full shields breakout on arena maps is playing. I mainly play team arena and dread getting breakout in the rotation. If we are forced into having breakout in the Team Arena playlist, I think I speak for the vast majority when I suggest that this new Arena Breakout replace the original breakout. I found myself more comfortable with these maps (because I play them more heavily in the rotation than the random breakout map) and having a lot more fun because of that.
Edit: On asymmetrical maps, switch starting sides each round or place weapons differently.
