add more arena crystal

plz add some more items to the arena crystal! right now there not worth spending the arena chips on with a very high chance to get gold and a slam for energon, so how about you add a exclusive bot like "Grimlock, mods and relics" other thing like boosts, ore-13, refill and/or shields.

I like the arena crystals, best way to get gold and you'll need it once you start hitting rank 3 with bots. An arena exclusive in the vein of the Punished from mcoc would be nice though, and Grimlock would be a good fit.
