Return Mangler and Blessed Penetrator

[Akanamah]

So in other words you want to sell all the stuff that you have that got nerfed for the value of what it was before?

Not certainly in that way.
Mangler nerf is absolutely unfair (even more I do not like his future updrade, but as I said about it, Winter will not allow me to speak)
As for Blessed Penetrator - I would prefer to return all that we spent on its buy (I repeat - buy, not - craft)
