The idea of a practice area where you can choose a specific enemy down to the level and signature rating and fight them with anyone in your roster is something I’ve always wanted to see implemented.
It’d definitely help with testing the strengths and weaknesses of your champ and it’d be 0 energy, 0 cost, 0 real reward, and doesn’t effect any missions.
I don’t think Kabam would implement this but I think it’d be good for testing buffs, nerfs, ability interactions and get a lot of players more skilled while adding some transparency as to what happens with certain champion interactions
