I thought of something like that a while ago and I thought about it for a while and concluded there's no good way to do that. The best thing I could come up with, which I still don't love,cis having robots with special effects (fire, poison, freeze, etc) and having a special spar for them. I still don't even like that. I think the med/attack robots should be removed entirely and pet robots should have their own effects, which will be minimal (a fair amount smaller than the current med/attack bots) but it's only meant to give that slight edge, not to affect the actual gameplay. Some robots would have no effect and would just be for appearances, while others might have small effects to them. I also think you should only be able to have 1 out at a time and something should be done to make them always have to be out and follow you or something similar to that affect. Require it to be out for you to PK (considering you have one, or we could give out a beginner bot too )
