Seriously, let's have this discussion. It's the only way forward. No amount of tinkering or overhaul can really save this game. I mean if you're heading towards a shutdown anyway you might as well try it.
Fans will still buy skins, you might convert a few freebie players to pay for some cosmetics. Players might stick around which is what this game desperately needs; A healthy injection of new but devoted players. Get those ques down.
Do we really need a paywall for a game that's struggling this much? Might as well charge 60 bucks and you'd have the same amount of players.
