The 8 thing is weird. Like, I FINALLY understood why it was 5 plates. Each plate is 50 health, so at full armor you're at 250 health (100hp +150 armor). So with 5 plates in reserve you basically had double your entire health (even though regen mechanics make it silly and actually a lot more). But NOW you're walking around with 650 total health if you're able to constantly heal. Why not 6 plates or 9 plates? 8 is such an arbitrary number.
At glance this seems great for people, and it definitely is in solos, but there's a hidden problem: Snipers. NOW when you finally rip a snipers armor twice and they can't just willy-nilly peak you anymore, they've got like 2 more good goes at it. Sniping was already a pain in the dick and made counter-sniping a must for squads and I don't even know how Solos work without double loadouts to get ghost AND a sniper/main. Don't get me wrong, more healing is always better in a game like this, but people are going to notice that one rooftop guy is going to be extra annoying now.
None of the other changes even really matter to me. I'd like to have seen a weapon balance for WZ, but I don't think that's possible because it'd probably be game-wide and fuck MP. I think a lot of the 60-round mag shit needs to go, as well as being able to hold 7 rockets, and of course always hoping for a heartbeat sensor nerf/removal. I run the double magnum snakeshot bullshit myself right now EXCLUSIVELY because of heartbeat sensors. I HAVE to run Ghost and I never expect to get two loadouts in one life so I have to run a main (usually a DMR/Sniper/LMG) and then there's no better alternative for the CQC than dualies. I WISH they'd let shotguns be a secondary and that would help immensely. Shotguns more or less suck in WZ and I think running DMR/Sniper and Shotgun is a very balanced combo. Anything past 20m and you've gotta be good or you're gonna be dead. Playing with the shotguns in MP is so immensely satisfying. You still have to ADS at medium range and quickscope headshot to kill, but it feels like you're actually doing SOMETHING rather than the SMG hipfire nerds who just literally run and jump and hold left click with their MP5's and PP's and shit. I'd love to bring a buffed up pump to help clear houses and deter rushers, but there's no way in hell I'm putting a shotgun loadout in WZ and most of the purple/orange shotguns right now aren't super great.
I didn't expect them to have an actual big patch for this with COVID shit going on, so it may be a month or two before we get a "balance patch".
