The original Warzone was messed up due to countless additions and implementations, which was unnecessary, but also necessary at the same time. What they could've done instead of piling up 3 to 4 games together was to just add a different set of weapons and maps into the original game, instead of merging every game one after the other. Yet, here we are now, even if it's a mess, it's still worth the trouble.
i'm glad you got your beta-access.
Luckily, I could manage some time to grind and test it out properly, but I'm not sure when I'll be getting the game. So far it seems like an expensive purchase that also holds quite a lot of hassle, and I'm someone who likes to maintain distance from such pesky inconveniences. Time will tell I guess, I'm in no hurry for now.
Maybe getting a taste of the Beta run of Warzone 2 will help me change my mind, but for now it's still 50/50.
