So basically it has come to my attention that there are many misconceptions in the game, and some things that people are not sure about

if there is something that you are not sure about, post it here, and I will endevour to get an official reply. I will start the post with a few that I have noticed

1) AP kills more sailors per shell

Absolutely false. AP does a different type of damage, and kills on average same number as HE per shell. 

2) AAW stat does nothing

Not true anymore. Devs have partially re activated the stat, and are continuing to improve it. (many people thought there was a t5 scout ninja nerf, which there was not)

3) Max number of Vets per sailor

is currently 40%, and as you approach that limit, it gets harder and harder to get it. I think the record number of epxerts burned to get 10 vets is something like 16k (was on old forums)
Sailor Info this page is useful to explaining vet conversion, and max number of crewmembers on a sailor :)
