I want an 'increased attack speed against wards' mastery.

how about a support mastery that makes your autos do 2 damage to wards?

Agreed. Wards take 10 hours to kill.

This would actually be really cool for supports specifically to get.

The vision game is really important, and no one emphasizes the vision game as much as the support does, while control junglers would use it well too.

I could definitely see this in the utility mastery tree either as an 5 or 13 point mastery. It's not worth it to be any higher, any lower it might be too strong, and 9 point is out of the question because it's a breakpoint mastery, and needs to be really strong to be worth it.

great idea
