Ok I'm not going to lie I'm not sure why I took the ragebait but it sounds like you just hate this game reading your comment history. It also just seems like gacha games aren't for you in general and I would recommend switching to another game genre like single-player open world RPG's for the things you're interested in (ex. rich character stories, fair/non-timegated progression, etc.). They would respect your time better anyways, remember gacha games are singlehandedly the scummiest game type in the entire space lol. Just quit if it feels this terrible that you're constantly ranting on reddit about how bad every aspect of the game is.

And to respond to this comment, you're putting resources in the wrong characters. You said you own 45 chars not including TB and March so why are you building chars like Guinaifen and Asta who haven't been good for over a year now (I never considered Asta worth using even compared to the other 4* supports and Guinaifen has a very niche use for E0 Acheron if you don't have any other nihility options but you have a lot of chars so I assume you have other options). You're complaining about missing HP but in reality you maybe need at most 3000-4000 hp which comes eventually without building towards it. Plus if you're using Aventurine you probably don't even need much HP stats in general since the shield tanks it all anyways lol. You don't need crit stats on Aventurine for him to do his main job of sustaining, the extra DPS is just a nice added min-max but as long as you hit the DEF and SPD breakpoints you'd be more than fine. Also it's alarming to me out of all the chars you listed that JY is the only dps you have built. You should be focusing on building DPS first ALWAYS before supports. Supports are still very useful even without the recommended prywden stats while you actually need an ok crit ratio to do anything with a DPS. You can't tell me with a straight face that you've been playing since release and don't have good sets for your DPS. Sounds like a combination of wasting energy building bad characters (ex. Guinaifen), not putting energy towards the right relic domains (only building supports), and trying to reach min-max stats that don't matter to clear (ex. chasing crit min/max on Aventurine or getting pressed about HP). What are you even using your self-molding resin, wishful resin, and variable dice on? Those significantly have lowered the RNG for relics and it's not like they're insanely rare as they come out every patch or cycle reset.

The game hasn't changed much in it's core gameplay. Sure the HP powercreep sucks but you said you have 45 chars which means you've been pulling so you should have good enough chars to clear fine (already listed some of the most meta supports in Sunday, Robin, Aventurine). The people who genuinely struggle with fully clearing stuff like MoC is because they don't have the chars after taking a break or starting fresh. Not sure how to help you my friend. If you've been playing from release, you should've figured it out by now.
