Thornmail was the only haven for Tanks against %Health Physical Damage, I think it needs buffing.
First off. The recipe price for thornmail is ridiculously high, so many times I've left fountain with like 600 - 1kgp because I can't afford the recipe price for thornmail which puts me at a huge disadvantage. It's not a strong as it used to be. Why not shave like 150 gold if not 200 off the item.
Carries options to get exactly what they want and need is ridiculous.
Oh hey I want to kill a health stacker
That's some sustain you got their buddy, or had
I need to remove this wall in my way
Oh darn those pesky mages or harassing me
Oh I need to take a hit while I melt these mofos

And tons more... All with special side effects that make them ridiculously strong hypercarries. Lets not forget every single marksman in lol comes with some sort of crowd control or way to avoid taking damage as well as chase/lock down their targets. I'm not opposed to this. But there's already a pretty basic advantage they have to non marksmen champs, range auto attacks that actually hurt... A LOT. Tanks need some love too, not the broken tanks like
but the tanks that hit like feathers and needs their team probably more than their team needs them.
