Make gargoyle stoneplate reduce true damage as well.

And then rename it "somewhat true damage".

Oh, and if you're a squish and cho manages to get in range of his ult.. it's fair :P

true damage should be affected by exhaust as well.

while we're at it, lets make randuins reduce crits by 80% and lets give ahri a dash on all her abilites

What seems to be the problem here?

or you know, keep the item as it is and give cho a base true damage with no scaling but his stacks and make the scaling magic damage only
