Sea Dogs "nimble" ability

[DGDobrev]

I totally agree with that Especially on impossible, these guys give me bonkers. They evade (almost) every second hit.

Well, generally, even with 20% that is plausible, because that's 20% for each hit UNLESS they evaded the previous hit. Although I must say that I have seen enemies avoiding 2 consecutive hits... But that was a rare occasion.
