Balanced Kenshi has been overrated throughout the whole game life. If not, he would probably have got true useful buffs and not the trizillion irrelevant buffs he has been getting that have ended up with him being bottom tier in every iteration of the game.
Nrs probably has been too scared all this time about making mk9 kenshi again, to give him actual changes that helped him.
The whole game's life? Who the hell has been saying balanced was good for that long? People have only been saying Kenshi is good(which he is now imo) really since the October patch, and to a degree people have been saying hes not dumpster tier anymore since XL, which is true, he wasn't amazing but he'd just climbed out the dumpster essentially.
Everybody knew from within the first few months that Kenshi especially balanced was trash, I never seen nor talked to anyone who said otherwise before the xl patch. He's never been overrated, he's in a fairly good position now, and while he still has some things that maybe could need buffing, he's now not dumpster tier.
Look, I'm not being rude, but you're crazy if you think Kenshi is overrated. I know you think he's terrible as you constantly mention, but to say he's overrated is a lie.
