Some skills are still rather elusive to me.

How do you use active medical skills, like first aid?
edit: first aid and medical tree fixed in the latest patch

Same with debuffs. While Psy works, bad mojo like bleeding or setting on fire don't seem to faze my enemies. Even though the effects are shown as active.
edit: fire and bleeding still doesn't seem to work? Freezing or stunning does

How many teammembers/employers/goofers can you have without investing in the leadership tree? I had two with barely enough leadership for one - even though one of the two was most likely only a temporary follower.
edit: one temp, one regular.

Is there a light source/torchlight etc.? Some locations, like a certain quirky cave is extremely dark which might be a good idea to search for hidden loot.

How do I apply skills like scrap metal tailoring? I can strip arnor plates, but I didn't find a workbench for creating new armor or fiximg/repairing equipment. All I found so far is a chem workbench and a workbench where you can build a few basic knifes and lockpicks...

How do you use the rod for cleaning weapons? My weapon is sometimes in a sorry state, because I never have found cleaning kits or something similar - had to switch weapons to reduce jamming back to normal levels.

Beside those questions I really like the EA a lot. Lots of things to try, lots of funny but pointless ways to die ;-)
