As far as different roles if you'll watch the play there are many support robots all ready on the field. Especially Natasha's as long range support. For modules, that sounds nice because the Jesse should have jump jets or DASH all ready. Im also a bit sad that heavy mechs, sorry ROBOTS, dont have 4 heavy slots or at least medium slots on their arms, like the Natasha.
Im wondering if the modules will address this?

Painting bots: could you just have a paint program that we could paint on the bots we have, maybe some stickers that could be sized like car racing games have. that would be nice. Just so we dont all look the same.

there are bots that can be purchased with silver or others for gold or the newer ones with those stupid puzzle pieces. Those I dont even care about because waiting for 10K pieces is ridiculous. I wont be spending real money past the amount I spent on sale items. At least they seemed reasonably priced while on sale.
