Evolving Armor behaving strangely?

[KelvinKole]

I just got a new bio/ma tank to the mid 20s and am not sure Evolving Armor is working right. 

 

According to the description, it sounds like turning it on should give a resistance bonus, and an additional amount per enemy in range. In application, if I have Efficient on I don't get the flat resistance increase until there's at least one mob in range. If I have Defensive on, I do get it and the additional amount per enemy behaves as normal. 

 

It's a small thing, but I'm not sure if I'm just misunderstanding the description of if it's a bug. The optimizer in me wants that flats resistance increase regardless of adaptation and mob proximity.

I think it performs differently depending on which stance you're in. Read the description of adaptation to check. I'm not sure off the top of my head.
