I've said all that about the helm long ago...
If it could be coded the negate the headshot only twice then not work it would be pretty balanced. Straight to body damage would probably be easier. I don't like the item at all and think they should just be gone.
If the person playing the vaga puts themselves in a situation to be sprayed upon.... well.. that's their fault.
The other items restricted... meh
I like the old health rings... they had the green line tracer when it healed so people wouldn't do that.
