Just ran a quick PVE battle which illustrates nicely what I’ve been saying:

As you can see my efficiency is way above everybody else because as a guard you farm the kill shots and the others didn’t exactly bother buff assisting me. If you do however look at the damage dealt and then compare to the experience received you can see it is roughly proportional for everybody regardless of what efficiency said (second guy obv. had a license). Experience translates into synergy but I still haven’t updated my log parser to the new formula or tried to figure it out in the first place so I’m only displaying EXP.
tl;dr: efficiency numbers might look off but you still get the synergy and the credits you deserve so it doesn’t really matter except for a few contracts (should be fixed because of those of course).
