THere is tons of improvemnts that can be made to this game. 


1.  Game modes that place  Nations vers nations
ie... USA vers IJN , KM vers UK .. ect  national battle  would  give a great  nation pride...

these rooms would have to be able to id the nation and auto move to  the team ...


World Battles  game mode....

 Axis Vers Allieds .... Biggest problem here would be what to do with MN .... As half was Vichi but was eventually  under Brithhish control...
Once again   SDE would have to make a Auto sort  so we dont have to wait for player to figure out what nation they are suppose to play with.

 Making  Normal rooms gain better XP.... ie   I like the fact of own xp gain is recieved... but for smaller ships playing in the same room  maybe a shared  xp if ship is 2 tiers under  max ship size....

Increase map sizes... if maps were same hiehgt as width would give  BB more room to maneuver (not stacking north and south)
.... this would reduce the need to reduce any planes  vision...
