Totally unplayable with subs ingame imo...last game I played Alaska, had 2 subs-X,one crossed the map killed CV in first 5 min of the game ..second played around 5 ships for 10 min absolutely invisible whole time..torps from all sides,enemy BBs snipe from 20 km,we are dodging torps from 4 dds AND A SUB!! You can't turn either side..There is no fun there-it is too much to put at one player that can influence the whole game-if you get a bad sub player-you are doomed for that game ..it doesn't matter how good is your team!? I really think-OK!!- put them ingame- but make it optional for players to choose if they want to play with or without subs.now you have bots -"ok lets play one with subs,we will dive and cross the map and make havoc" Players are than chasing one sub ..cant focus on the rel gameplay..MAKE IT OPTIONAL!!!!
