>Win rates seem pretty balanced between the factions
Who gives a shit? You can balance win rates in any dogshit unfun game. Winrates are completely meaningless until the game itself is actually good. Balance is the last thing to matter. A perfectly balanced game in terms of winrate can still be a miserable experience to play.

The game has become so abstracted as to be cartoonish to the absurd. It's soulless and non-immersive. Customization has almost completely vanished. Scenarios are silly whacky arm-waving balloon man nonsense about standing in Very Important Circles just a literal stones throw away from several other Very Important Circles. Morale is a nonfactor, character-squad-attachment mechanics are blitheringly moronic, battlefields are much too small with points too bloated, bullets can still magically fly around corners due to the idiotic line of sight mechanics, there are no overrun mechanics so a literal single grot can stop a land raider in its tracks from moving, still no armour facings or fire arcs so a leman russ can fire every weapon out of its butthole and shooting it in rear armour does nothing different to shooting it in the front, both meaning maneuver and positioning are meaningless, abilities all feel like gamey MOBA shit or just a re-roll buff, faction identities have been weakened and homogenized, frick I could go on all day. Every single clause in this post could have a multi-page dissertation alone written on how detrimental it, or its lack, is to the fun and cinematic gameplay around which 40k was originally designed and intended for. I have never seen the fun sucked out of a game to such a degree, not that 9th was exactly stellar itself but 10th doubled down on most of its problems while adding whole new ones and only fixing like two things.
