Because I'm always right I'm gonna put my thoughts on the new units here:
Roana will find use against SSB/Lilias/Charles/ML Ken teams but because she offers less than nothing against Arby or any unit that doesn't rely on extra attacks she will not be seen on defense teams or be of much use against the myriad and nearly endless parade of Basar/Arby/SSB/(insert cancer here) teams. Basar in particular lols at her S3 and S1 and nothing has changed on that front. Easy pass for me. I guess if you have Aywin built you're pleased as punch with her (especially since he is VERY likely to get buffed in the coming balance pass), but since I'm not a gigawhale with endless mystics to toss around I don't have him, so yeah.
Sinful Angelica is in a weird place. She basically takes Diene's slot, but since she offers zero defensive utility you're gonna have to rely entirely on her teammates to keep themselves alive. I can see her being particularly strong on, say, a LQ Charlotte/Tywin/S. Angelica composition in GW against Arby comps since LQ Charlotte doesn't give a fuck who's protecting Arby, she'll just nuke him to 0 flat without even an attack buff or def break, and with S. Angelica's heal it doesn't even matter if she goes second since she'll literally restore her entire HP bar. This is significantly less viable against double revive comps, however, due to S. Angelica's 2-turn immortality duration. I guess it depends on whether or not her S1 dual attack makes up the difference. She seems strong, at least, but very, very weird. You want to build her very fast and with high enough effect resist to not get immortality stripped, and her HP count is literally irrelevant for the 2 turns that her immortality is up, so she's easier to build than most support units, but it is VERY damn important that she goes first. Last thing you want is for the opponent to nuke her before she can put up her immortality. Speed racing memes are eternal, sigh.
Basar still kills the fuck out of her, though. I don't have a big enough "sigh" for this. Give me a break, dammit. And don't tell me to roll a ML 5-star that doesn't even invalidate one of the bigger reasons he's such a problem (his 30% CR pushback).
In other news I fully expect to be disappointed again with the coming balance pass, but what's new, eh? I wonder if they'll even touch ML Leo and ML Romann after they've been hanging in the wind for so long. Weird that they weren't addressed in the previous pass. And since Tempest Surin is "too recent" a release I get to wait until fucking June before they even look her way, despite the fact that her mediocrity was obvious from day 1. Thanks, Super Creative.
Imagine if I used BBK instead. I could literally just raise her and stick T. Surin's gear on her and do twice as well (thanks to her higher multipliers and extra turn on kill). Funny how that works.
Anyway, yeah. Neat units, but nothing has changed. Basar king forever. /shrug
