Who to rank up (5 stars)

DadouSan

I've been VERY lucky on the Valentine's event.
I have 1 awakening gem for each class except virtuose.
I already have a dupe Cap IW 5r5 and my r4 are Starlord (d), Blade (ud), Quake (ud), Ghost Rider (ud) + 6r1 Angela (d) and Sabertooth (ud)
The rest is not worth mentioning.

Ragnabro

If you need bleed immune you have very good options
