This have been said before in a lot of posts, but i havent found one neither in suggestions nor in general. So I make one exclusevly for this one here.
With officers and frigates being lot more stronger now it has become really really unfair that enemy fleets can have unlimited numbers of officers. This has made slammel ships much harder to kill and not only made fleet battles harder, but the real problem is that it made it much longer and therefore more costly.
There should be a limit, maybe it should be higher than the one for the player, but this much is just unfair.
