Okay, Nya can rest easy now because I no longer consider MK a huge threat. But I do think he could use some changes. As in, things that would still keep him as a powerful hero but would make it a little easier to predict him. For starters:
Death Blossom is fine the way I see it. If anything, I'd make it so the second hit on every enemy can't Crit, and that the first hit on every enemy has an extra chance to Crit.
I think MK should lose Wushu. As a passive. But instead, Vibrating Palm would give him Wushu for 3 turns after it's used. It could be called Channel Spirit or something, and be made into a Spirit attack. Seriously, what's a "chi attack"? Like I know what Chi is but what's the point in making just this one ability it's own type of attack?
Let's talk about Tenacity. I don't like it. Not that it's unfair, but it's unpredictable. Messes my strategy up not only when I'm fighting MK, but when I'm using him, too! I think Tenacity should be removed, but then given as a buff for 2 turns after Dim Mak is used. Then! Then change what Tenacity does! I think Tenacity should be a GUARANTEED attack, at the end of every turn it's active, but MK can only use basic attacks with it, and Epic attacks can't proc from it either.
Additionally, MK could start every dungeon with Tenacity and Wushu applied for 1 turn each.
Please tell me your thoughts!
