I didn't realize first aid/armor patching xp was based on the level of mob killed - I thought it was the level of kit used as long as you were in combat within 60 seconds. Your description of the way it actually works now makes me want to spam level it ...

I like the idea of it working based on actual healing done but it's pretty easy to lower your health yourself without any risk. There's drinking fuel oil, and even easier, you can switch from a naked loadout to a fully-geared loadout - for a few seconds there, you'll have a lot of health and armor to regain.

Maybe if xp was based on actual healing done as long as you were in combat? Although I do like the idea of getting xp for healing hypothermia...

First aid and armor patching could certainly use something to make them more exciting, just not sure what. I do like it that the chance to use up a kit has gone down to 10% in the latest patch - as a frantic hoarder, this makes me far more likely to actually use the abilities naturally, rather than just when trying to level them or when I'm about to die.
