-CS2 is the end of community servers for Counterstrike
-Surf, Bhop, and any community server that required Source Movement plugins either doesn't work at all or functions way more poorly than it did in CS:GO
-The community server browser is just a tiny icon most players won't even notice
-The community server browser UI in CS2 is way worse than the UI in the CS:GO server browser
-Updates lack new game content
-Mostly engine updates instead of new content
-Hits/Gameplay feels different after every update (Some people may say this is a positive but I noticed it makes the game feel too different between updates rather than it feeling about the same every time I played like it did in CS:GO. It's like Valve often changes their mind on how they want CS2's game engine to function between updates.)
-New sub-tick "system" feels ass
-Mostly cosmetic updates
-Addictive slot machine virtual item gambling case system mechanic children have access to
-The addition of too many cosmetic items
-The beginning of the game losing it's original art-style due to too many cosmetic items being added
-Cosmetic items are changing the art-style of Counterstrike way too much from it's roots as a mod for Half-Life. It's similar to how the Call of Duty series lost it's original art-style as a gritty military shooter and instead formed a new identity as a game with a ton of pop culture related 3D models you have to purchase through in-game microtransactions like Fortnite. It's easier to advertise a game as a pop culture celebration than it is to advertise a gritty FPS game that has content that is inappropriate for children and may scare away a more mainstream audience from playing. Plus, Valve has an incentive to add as many microtransactions as possible to maximize their profits.
(BIGGEST OFFENDER BEING THE FEMALE PLAYER MODELS!!)
(ALSO VALVE STOLE THE KEYCHAINS FROM RAINBOW SIX AND THEY WERE NEVER GOOD IN RAINBOW EITHER!!)
-Pay to win player models (not true for every paid player model but some player models have easier hitboxes to hit than others)
-Pay to win skins like the SG 553's scope being easier to see through with a skin equipped than without one
-Anti-Cheat barely ever detects cheat software
-Stuck in matches with players using wall-hacks/aimbot on my team and on the enemy team
(straight up spin bot on a bad day)
-Pros get caught using cheats
-Stuck in matches with players griefing objective, racist voice communication, teamkilling, body blocking, afk, etc.
-♥♥♥♥♥♥ buggy engine and menus
-Game often crashes in the menus when I'm alt+tab'ed or when I'm loading in
-Overall a downgrade mechanically from CS:GO

Better in every way compared to CS2
