IMO you cannot compare PUBG to COD. COD is an arcade shooter with silly nonsense like sliding etc, little strategy.
no one is comparing the "strategy" element to COD/APEX - What people are saying is that PUBG has fallen so far behind in terms of improving the basic mechanics of the game. How slick the attachments are/looting/movement ?? They are miles and miles off with this part of the game.
COD/APEX and PUBG are different games but the devs have failed badly in terms of dealing with the things that matter. Sprucing up the graphics etc is not what they should be focusing on, Look at valorant, looks like something from 2000's but the gameplay/slick movement/tactics are spot on for what people want to play. PUBG devs have focused on completely the wrong.
Gliders
Pink Weapon skins
Outfits
High heels
Dinosaur costumes, wizards and S&M outfits
Never mind the important stuff like - cheaters/desync/gameplay/movement/looting etc etc
but Warzone, I barely feel anything other than a little excitement
