4Game

Cons:
New equipment meant to save credits means spending gold instead
The one-size system for equipment classification doesn't work:

-Lights: Spotting (totally fine)
-Mediums: Mobility (Not really fitting but sure)
-Heavies: Durability (French heavies start to cry)
-TDs: Firepower (Makes enough sense for the most part)
-SPGs: Nobody really cares and I honestly forgot because I also don't care

All equipment now needs gold or a demounting kit
New UI is pretty terrible across the board in multiple regards
New font in the team list is terrible and way too small
Light tank equipment now contains way too much RNG to predict, also removes the "proxy-only" effect.
Equipment lets light tanks run around with 50%+ camo rating on the move
The old communication system was replaced with a very unfinished new system that doesn't even have sector pings or affirmative/negative commands. Positions are marked very vaguely on the map, and most of the time won't be used by the team anyways.
Didn't nerf the Lef

Pros: Buffed certain non-russian heavy tanks
Added Pearl River (and it's fine besides the rice field)
Added the polish mediums (and they're fine)
Nerfed wheeled lights
Bonuses are added to matching equipment categories

Neutral: Bonds can only be consistently earned in tier 10 vehicles, and there's a hard cap on how much you can earn daily.
(Semi-unrelated) Chatbans are happening more often, and for lesser reasons.

I rate this update a 3/10. Some of the new equipment is cool, but a big part of it adds way too much RNG to the game. In their attempt to save players credits, they are now forcing players to either wait for a demounting kit, or spend gold. The communication system in-game is so terrible in regards to actually communicating with other players in random battles. The likelihood that you get constructive teammates that know how to use the system and regularly will use the system is so rare. The one-size system regularly does not work for many tanks. This update is very unfinished and was pushed to be finished just to update the game. If making the game like this is what we had to do to get the wheeled lights nerfed, it wasn't worth it in my opinion. This entire update could have been so good if they had just taken their time with it and actually tested this thoroughly, because they clearly test half of this stuff.

Criticism is appreciated in the replies, this is just how I see the update. There are many, many, many problems with this update that were problems during the beta, and are still problems now that the patch is live. I'll definitely be playing the game less until this get sorted out, because there's just too many balance problems that need to be fixed with just this one update.
