Thank you for your efforts and all upcomming new ideas! Good to see a very active developed game.
I like the idea of karma, binding the players to the decition they make. this could improve the worth of the flag you carry.
The only problem I see is that if you can pay off the karma, the whole idea gets neglected for the vets, while it is very punishing for new players (who maybe don´t even understand that system right away).
My suggestion: To support the devs I´d even pay for a "Karma DLC" that is working like the forger DLC maybe. So you can reset the karma and your relation with other nations once in a week or month p.e.
I think the idea has potential to decrease the random ganking all the time and could bring a silent/stealth alliance system if clans have to communicate whom they help if they want to pvp together.
Maybe the players who always try to make this game a historical version of WoWS with lobby fights and random sinking won´t like that. But for a beautiful simulation it is surely a benefit to bring a system into the conflicts like that
Then maybe the nation with 60%+ of playerbase in it should split up. With 600 guys online I don‘t have any problem to find someone to tag
