I'm actually really looking forward to this MMO. I prefer my MMO's with more players than MMO's like Destiny. And since BF1 supports literally 10x the amount of players, I can't wait! The progression system that they have brought up from other games will be decent as usual. Not happy about the impending P2W where you can just purchase progression. I love that my characters progression is persistent at least.
I skipped BF4 as it was just more BF3.
