If Thornmail is getting hit, can we...

improve the build path for it?

Simply make it build out of two chain vests. If the current changes to the price go through, it'll have a combine cost of 1250 gold. The highest combine cost in the game. More than Guardian Angel

I know Thornmail is currently very strong, so I understand that you're nerfing it (I still remember when I was learning how to adc and I asked a more experienced friend what I should do when an enemy bought Thornmail and his response was simply "Don't attack the one with Thornmail. Period."). However, it doesn't need that sort of combine cost. Improving the build path will make the nerfs a little less harsh, since you're hitting both the effectiveness of the item AND the price, but without making the completed item any stronger.

Please?
