I'll probably use it on Nahida, although I'll have to see if it's worse than an R5 Sacrificial Fragments in terms of utility.
I use sac frags on her and the passive is mostly useless cause her skill has 6s cd (unless you missed it on cleared the instantly), it's just a 4* em stick and citlali's weapon is a 5* em stick with +100 em for free.
I lucked out on one on my original account back during the 2.X patches, however my current account has been utter dogshit when it comes to giving me anything good from standard, or any good polearms in general. What am I supposed to do with the fourth Tighnari in a row??
At least white tassel is genuinely viable on arle. Assuming bennet buff, Deathmatch is only 3-5% better allegedly. The event spears are really good too, the next patch has a ER spear that gives +40% atk and 40% atk speed (!) for 10s after skill so sadly not great on arle (no uptime). Because mihoyo loves giving us more xiangling spears.
Use him lol, tighnari is not top tier but he's viable on some single target bosses with only 3* bow. His cons are also relatively good and "at least it's not 4 qiqis".
Just barely dodged a bullet, sometimes you craft a perfect artifact and it all goes into flat defense or some shit.
Thats my greatest fear and it held me back from crafting anything lol. They're going to buff elixir-crafted artifacts to ensure the first 2 rolls go on the selected substats so wait until 5.5 for the next one if possible.
My arle is 92/154 on gladiator so she's fine for now, guess i'll make a emblem crit hat cause all the 4 i have are mid.
If it helps, characters that don't depend on crit values can be useful if you don't wanna do the mind numbing rat race of farming artifacts — reaction teams with Hyperbloom, Aggravate, etc were extremely strong and are still good now, all you need to do is stack enough EM from your weapon and main stats and you're all set.
Agravate/spread still wants as much crit and dmg bonus you can get but also some decent EM so in my experience are not that much easier to build (EM is rarer than atk afterall).
Hyperbloom is pretty easy tho, you only need nahida and kuki with full EM (you farm that on the same domain), then put a hydro enabler. If anything it lowered the skill ceiling so much it was responsible for sumeru enemy powercreep.
