I had 7HH passes and as is typical, I pull until I rip out the guaranteed 5*+. On my first fucking pull I get Eyja, who was probably my most wanted unit outside Warfarin/Ptilopsis. The last 6 HH pulls were absolute dogshit. So, I'm reluctant to rip a 10 pull as the only other unit I'd really love to have is Ifrit (have Silence and Lappland - could give a shit about the meme machine that is Mayer). I'm thinking of saving my 3ish 10pulls for Chen, but the other units on her banner are total junk if the rumors are true. I'll see what the banner has tomorrow and if the rumors prove true, I'll probably rip another 10, praying I land Ifrit.
In terms of other E2s, don't forget that THICC bitch Cuora. She's also relatively "easy" to E2. Saria also gets stupid at her E2 as well. Not so much because of the skill, but because of the talent.
