If you want every piece equal play checkers
And I think your interpretation is extreme. I said previously I think the Prisoner could be nerfed - he does give too much of an advantage. But I think the nerf was extreme. Why pull a 5* if he doesn't give a significant advantage over a 3*? What's the point?
I don't want a game where one toon gives such an advantage it's frustrating if you don't have that one toon. But at this point I think the Prisoner the only one that fits that bill. Are there other strong toons that are challenging to face? Yes. But if they were that OP you'd see them in every defense. Almost anyone who had a Prisoner used him every time. He's that good. And every one else wanted him (OK - Aristo didn't

)
GRE? SSD? You see a lot of them. But not on every team.
I do think the Prisoner was castrated. I think a more gentle nerf would have been possible and from comments many agree. Maybe I'll be proved wrong - maybe I won't be. So while I respect your opinion and your right to disagree (discussion is why forums exist) - Im not understanding your need to tell those of us who think differently than you to stop expressing our opinion.
