More permanent character items from Achievement System

Currently there is only 1 permanent item from the "achievement" system. The weapon master's mask (which look pretty bad IMO).

If there are more permanent character items in the achievement system, i would love to grind for it. And it will actually feel like an achievement. I am sure a lot of veteran players would agree.

Personally, I think it is a better way of rewarding player for playing hard than giving out crates that they have no choice over.
After all we value more for the things we worked hard for.
