The party issue is huge issue and it's across all 3 game modes. I really wish they went towards fixing that instead of the weapon balancing they keep doing.
The whole Cryptokeys and COD points were always coming, though, I'm afraid. Which really sucks because COD points weren't a thing in the beginning but Cryptokeys were and anyone who's played a mobile game knew where that was headed.
And locking guns behind that--or anything really--sucks. I like to earn my gear not gamble it--which is what that system and others like really are about.
Specialists are fine, though. I think the addition of different abilities shake things up a bit and having some personality in the multiplayer doesn't hurt.
And man, I can speak for the movement system. I grew to dislike AW's and BOIII really brings it down several notches. Battlefield 1 has really grabbed me by the balls, considering I've always wanted to see WWI and just more historical shooters in general.
As for AW, I'm still going for it, not just for the COD4 remaster (though that's a huge plus of couse), but after Ghosts and MW3, I'm not expecting much.
