Ok, I did not find any other thread like this so here it goes: A random codex arena. 20 minutes into each day, every team ends up with the exact same builds which frankly gets quite boring. If the arena was random, it would make the experience more exciting then just plain mirror matches.
yeah he's saying like if you were a warrior, you would join a game and you wouldn end up with a random warrior build, of course weapons would have to be provided to you if it was a hammer build and you only had axes, but isn't that much like what the current costume brawl is doing?
