1) speed(against getting hit))
2) deck armor(against long range/high gun angle hits)
3) bulge armor(against minor underwater explosion)
4) belt armor(against close range/low gun angle hits)
We did a fun match with BB5 with only HH and no guns. I super armored my H44 in deck and belt and bounced everyone xD.
Depends on what kind of ship you run, if your in DD, torpedo and run, in a CA, range it with guns and run, in a BB, seriously, how did it get in range in the first place?
