Since I couldn’t add my input into fenrir’s thread I’ll just have to put my shit here and hopefully others can add on. IMO best grooves for her are any with run, it drifts and it opens up many offensive opportunities such as running lp, hp, hk for drill. Many of her combos are built into her chaining normals like l.lp, l.lk, l.mk, sweep. Her combo potential is nothing shy of pure insanity:
lp, lk, mk xx soul eraser
lp, lk, close hk xx darkness illusion (my favorite one :D)
More input would be appreciated.
