Play against our own roster

Sounds cool, but if I put a my droids against my exact same droids, RNG decides who goes first (and most likely who wins.)
I'd prefer a for funsies real time (or both optional real time and AI) match against fellow guild members that has no reward and no cool down. It'd be totally sweet, this way you're not limited to the same 5 arena matches and GW (that nobody likes) every day
