Hi, I don't know if these have been suggested and don't fancy trolling through 115 pages to find out so....
Firstly... increasing the Division size from 3 to maybe 5?? I have a few mates who play and only having 3 spaces means 2 have to be left out
Secondly (and this could benefit from the increased Division size.....) new game modes for if you do have 5-6 friends all together or even a internal clan thing...
couple of ideas I had were
1. Hunt The Bismark .... If you have 5-6 players in your division... 1 player is randomly picked as The Bismark and the others have to hunt him down.... in this mode the Bismark can have slightly higher HP and Reload time to make it a bit more fair..
2. Catch The Rabbit ... as above but 1 player gets a fast nimble destroyer and they have to sneak into the base.. blow up either a building or torpedo a ship... and get out before the other players find and destroy him...
I do have some more but i would see if anyone responds to these first ;-)
Happy sailing
