Do I think KV8 is OP, hell yeah. I hate seeing the damn thing on the field. It gives the biggest noob ability to force me to retreat/hide and forces me to tech/buy units I may not necessary wanted to go for.
Would I like to see KV8 nerfed? Yes, I would. Providing that commander it comes with gets properly balanced with nerfed KV8. Why, nerfed? for reasons I wrote ^ there.
Do I think KV8 makes commander, it comes with, OP? No, I don't. So far, other then pissing me off, I haven't noticed that I win or lose more games as direct result of KV8 being OP. In greater context of ultimately wining or losing the game, I haven't noticed that I lose 60%+ of games when I face Kv8 commander .
This to me, makes perfect sense. I simply can live with KV8, despite not liking to see it face me...
well is2 and shock troops got a buff and cost reduction this patch. so one kv8 commander is now much better.
