...On-topic,
a few general notes:
+Highest Hunter ATA - Can perform certain combos with certain weapons at earlier hit% than other hunters and as such has comfortable leveling progression. Will also hit some stuff noticably earlier on optimal gear such as Vjaya and Dark Flow.
+Traps - All of them are uses, and almost everybody knows Freeze traps are bonkers.
+Hunter and Female arsenal - She doesn't have HUcast ATP, but she definitely has *enough* ATP in many scenarios to make most of the HU gear work almost just as well (DoB is kinda the most unfortunate one imo, still worth using but it won't be anywhere near effective). Last swan makes her more a class of her own.
+Highest effective EVP - Underrated. Actually has really good stuff but its kinda hyper optimization. The inclusion of POSS and Jizai reaches breakpoints very akin to a physical-based ADR. Handy if something goes wrong and you want to preserve low HP for Dark Flow usage, while not needing to heal.
+Superior dagger/double-saber animations - Notably faster with daggers compared to other classes, she can re-proc s-reds more consistently between down-time and can reposition during twin blaze. DLS also comes alive due to speed and momentum.
-Lowest Hunter solo ATP - Its workable, but HUcaseal will struggle dealing damage in solo compared to other hunter classes. Early on they rely more on safer, prolonged combos. She'll be fine in the 180-200 range but yeah.
-Slowest overall trap growth - Though RAcaseal has slower freeze trap growth, I'd argue HUcaseal's the worst overall. She will max out damage traps at 162 (which is already late) and her freeze/confuse traps cap out at 180, which is late especially for a HU.
-Limited effective range - She offsets her range ability on singular targets with LS, but she lacks the ranged group control sans support roles like Arrest. You have DoB and Orotiagito but both are kind of lacking even when sphered. Its a good thing Vjaya exists (or if thats expensive she's decent enough at Yunchang too, but you'd need to trap) otherwise she won't be spicy with grouped mobs in general.
-Female saber animations - Sabers are less useful compared to males due to lack of forward momentum and slower animations. Excal is more of a defensive option rather than a offensive one.
I once agreed on the notion that there's no point in starting the class besides aesthetics but playing both HUct and HUcl and diving in the different things you can do with varied gear setups I'd probably never agree with that notion anymore besides sandboxed gear. The combination of having traps, the right arsenal and the right amount of ATA/ATP/EVP, she's just a nice versatile blend that just about fits anywhere. She's the unfuck button, its why I prefer playing her.
