Looks like Christmas came early as the game welcomes
Zhongli and Xinyan to the roster. PR has been going all out with Zhongli's ad campaign prior to the banner.

I hope to get Razor or Xinyan on my next round of pulls.
curious if it will make more money than klee, that banner made like 150 million in 3 days or something. otoh never underestimate the power of fujos...
you could get razor first month for glitter (imo he really looses a bit at higher level, if you got xianling she's probably more versatile). xinyan will be in the standard banner after 1.2 (and probably in the shop at some point), so if you only care about those two might wanna save rolls for later (and depends how close you are to pity etc.)
As for how I felt for the game itself, I'm nearing AR35. At least in my game it's becoming an EXP and money vacuum with the big lot of characters I'm taking care of. My biggest regret would be not focusing on a main team instead of switching between characters for different enemies. Trying to make up for that mistake before hitting AR40 or so. On the bright side though, co-op with friends was great fun.
it's not too bad, you want your supports at least 60 in the end for the last talent, some chars can be even lower. and that really only matters in abyss and possibly storm terror, the rest you can get carried in coop. there's also no need to level as fast as possible, it's gonna take you a few weeks to raise AR anyway and that happens automatically while burning resin, plenty of time to farm stuff.
after 35/40 check when domains unlock, can't remember exactly what unlocks when, but between 40-45 it's better to farm weapon mats, since the last stage with the best rewards unlock at 40, and talent books only at 45, so focus your resin on that (iirc, might get the level ranges wrong. just check what unlocks sooner and change accordingly). artifacts before 45 is a waste of time and resin, the drops you find along the way should be able to carry you up to 45-50.
also blossoms are a good source as well, even when tards on the internet whine about efficiency. first of all, you need it for the battle pass and you constantly gonna need the exp/mora anyway (yes, events have better ratio, but events are time limited and have limited quantity), the mobs still drop shit you need too, and the real farm starts after 45 with artifacts, which have such a shit dropchance for the good ones might not even bother with it.
