wait you are using the PE to hunt BBs? hmm.. guess that's acceptable if you have the 11" single guns fitted. I thought you were AA-ing. did you try that?
also, what guns did you use on the Gneisenau? if you use the 11" tripples, second set L, you will have the best range of any BB2, better range actually than all BB3s and some BB4s. You're playing KM so range must be your thing. If you are using the 15" twins you will have much less range and this will mean you get shot more often. Maybe that's why you dont enjoy Gneisenau?
