Anyone else scared of the new Blood Razor enchant for junglers?

Isn't one of the reasons the last iteration of devourer was nerfed for ranged champions was BECAUSE of synergy with % maximum hp damage champions like vayne and kindred? So now they're making it give % hp damage on every auto?

I'm skeptic, to say the least. I do NOT wanna see vayne with smite again after last season. Kindred is already strong, giving her more tools to shred tanks without having to Hunt seems...busted. Kog'maw jungle just started looking rediculous again if you can afford a carry in the jungle. Kayle can now shred tanks and pretty much anyone else in the vicinity with ease. God help us if Kalista figures out a way to work with this.

Paradoxically, I think champions such as Yi, Shyvana and Warwick will remain about the same. We may see a remergence of tigerdyr now that his AP variant has been suitably nerfed. I'm honestly not sure about anyone else.

I'm not trying to be a naysayer just to naysay...but adding another item with health shred to build on top of BotRK just doesn't seem like a good idea.

As a tank...wtf are you supposed to build to counteract that? Only thing I can think of is something like Frozen Heart + Randuin's for the attackspeed slows and pray to god your mid and AD are fed enough to burst the people they need to before you get completely melted.
