I actually liked the idea of a battle royale in cod. At least in my opinion I feal as BR fits well with cod. So far I have not ran into many issues in Warzone like bugs and what not. And the Season Pass isnt that bad either.
If I were to complain about anything it would have to be about shotguns, as them needing to shoot someone through their armor 8 times vs like 1 in multiplayer. Other then that I havnt ran into many glitches other than a funny glitch as we killed our teamate with an rv going up stairs aparently.
