@DoYaSeeMe They are releasing a patch/update for the stuttering & lag, so hopefully that'll be fixed for you. I have not experienced it once in my 40 odd games tho. I did see other ppl mentioning it.
I tried Warzone when it came out... alone it's even worse than Apex because one of your points; map is too big. If you're alone and your teammates don't communicate, then you seem so insignificantly small that it's not even funny. You can easily squadwipe, but another team will be on you before you know it... especially if you're in Downtown. I avoid that place as the plague XD.
When playing with 1 or 2 buddies the game feels entirely different tho XD.
But since solo's is up and duo's is to follow, the game will be much more fun to play :D now they only have to get rid of those camping sons of guns and it's the perfect new BR to play...
