I agree with InfamousNova about having a lock/unlock feature via the Home Menu & Bleeding Out Menu.
Unlocked after you've respawned and left your former body for clean up.
Maybe making a Medkit unremovable from a Medic backpack regardless of locked/unlocked status, same way only a sniper can use sniper rifles, auto riflemen only using auto's etc. I haven't tried playing another role and using a Medkit to 'revive' a player, unsure if that even works?
I've witnessed a few times in regards to the original post's example, a revived Medic minus his 'borrowed' Medkit happily (hectically) shooting away to defend the HQ, while others are bleeding out around him/her and offering some very hostile comments about 'not playing your role as a medic'.
So that got me thinking about locks and stuff, and unlocking to give people access when needed.
My example is just from a Medic's role and I'm sure it would be welcomed playing other roles.
So, it's not a MAJOR issue, just would be a cool feature. Thanks for moving on this Quik, I know your always flat out man, and cheers to others for the feedback!
