Not that I've noticed. That isn't, of course, to say that the game was healthy to begin with. Tiers 2-5 are effectively dead - all the ships I own in these brackets are utterly pointless. And, of course, everything above that is more of a wasteland than ever.
My interest in plummeting. There's nothing like getting a match that's 2 carriers, 2 subs, 5 bbs and 5 destroyers per team - which is a lineup I am seeing more and more. Overall, subs appear to have effectively set fire to what remained of the corpse of the cruiser playerbase, pushing remaining supporters of surface ships into BBs or DDs. Everyone else joined the plague-bearers in one form or another.
Honestly, I cannot remember the game being in a more sorry state than it is today. And we have nobody to blame but the development team.
