Mobility

A long time ago, you could spam potions and be fine. Nowadays you can't use a potion and a skill at the same time.

I believe that only works for buffs. Because I can totally use a potion while I'm using triple throw. And gunslingers can totally back me up when I say that recoil shot doesn't cause this lag at all.

If anything, compare it with teleport, I guess, but longer time without a potion. Heck, you can't even throw stuff from your inventory in midair.
