Yeah Hyoh is so far behind now no one even compares to him lol. Even rough math of expected enhancements puts him DOA. Either way if you have Esther I wouldn't feel a huge need to UoC for another chainer right now.
And yeah I can build my Sylvie is insane tankyness. Like I can do the hp parameter with her while still having good def/spr.
As far as the others I'd put Lid over Loren right now assuming you can do a decent portion of the ehnancements. Of course if you have any other 7* breaker I probably wouldn't bother.
Yuraisha is nice but not sure I'd even call her a jump over all the buffers you currently have and more say she brings different combinations of skills than the others
In other news some people opening the follow up tickets... and I hadn't realized they changed the pool. Way too early to tell but it does seem like fears of them diluting the pool were merited. Seriously wtf are supercites in there!?! So making it seem more and more like plat is the way to go with the coins
