Yeah I agree. I see the arena as a big -blam!- you to everyone though. Probably little or no cover at all. "You like the rock in the lamps? How about a big empty room? Try hiding now." I'm concerned that they are so worried about cheese that they will wipe anything resembling strategy off the table. They are probably looking at nerfing the obsidian mind/ bad juju combo for the arena. Or the Titan bubble inception.
