I know from just text, the question comes out as condescending, so let me clarify. This is also gonna end up being kinda a rant of why I'm not really interested in the game anymore, but honestly if you don't care about reading that, you can skip to the end.
I've been playing since launch, and while the beginning was fairly fun, after you catch up to the story and start farming things, the amount of stuff you need to farm starts dawning upon you. The amount of time you need to farm mora, EXP, and talent books is already daunting, but then you have artifacts which are arguably the biggest factor on how big your numbers are in battle and is one of the most random factors due to having a random main stat on every drop.
This is the biggest reason I feel most people say to concentrate on only 1-2 DPS and ignore everyone else, but then why even bother rolling new characters for gacha? I feel like part of the fun of gacha games is rolling new characters to get new coverages and better combo dynamics with characters you already have, but if you are discouraged from deviating from your main DPS units, then that's not really a thing. And even if you tried you are back to spending a lot of time farming to stuff to get them caught up.
This would be somewhat fine if the gameplay was also deeper or shallower, but it's in a weird middle place. The combat is very basic with everyone having only 1 main uncustomizable combo, and from what I've gather, the main gameplay to be having everyone spam bursts and then having the DPS keep whacking the enemy with the same 1 combo with occasional skills sprinkled in. Then repeating this over who knows how many times for bosses and and domains to the point where it seems like a job. The feeling of hitting enemies is also very blah and unsatisfying, but that's a different issue.
If the gameplay was shallower, that would also be ok in a way, because despite people crapping on "lol jpeg move wow gameplay" it's a lot easier to multitask daily things and do it while at work for example or watching youtube, and being able to stop midway and picking up a fight later on is nice. I will admit though, that I am not informed enough of the mobile version, so maybe farming and using up your resin so you can get on with your day is a lot more natural if you are a mobile player.
TL;DR the daunting thought of having to kill the same boring repetitive bosses and do the same boring domains, possibly over 1000 times in a year (maybe an exaggeration? I don't know) to help power up characters in a mediocre-feeling battle system has really started to tire me down, especially as a PS4 player who cannot play on the go with mobile.
In the end my question is, how are people still enjoying this game, as in what is your mindset to enjoying the game? What keeps you coming back and not feeling like it's a job? I am very curious, especially after a month or two after release, if people are still invested enough to keep playing for the long run.
