People need to stop defending the new Thornmail

Let me start by saying this : I'm perfectly fine with the concept of the new Thornmail. It's supposed to be more efficient against life lsteal while being less punishing for people without lifesteal.

What's the problem then? It's less efficient against lifesteal than what it used to be if the enemy only has one lifesteal item (which is usually the case). Even if new Thornmail applies GW, the enemy heals more through it than the damage they take, which was not the case with the old Thornmail.

The new Thornmail also has good things going for it though, it's more effecient against champions with two lifesteal items or with built in healing, and also halves healing from outside sources. But, these things are more situational and makes Thornmail less constant than it was before.

Finally, the last problem with the new Thornmail is the price, which is not justified even if it has the potential to be more useful than the old one. It's less cost efficient than it used to be.

tl;dr : The new Thornmail is generally less efficient and more situational, while getting it's price raised for pratically no reason.
