What unit you sending out as support

Depends of what you need. I have never used him on a horse team, so no idea about how he would do.

Not if you have Camus. Berkut basically has one or two points on him in a couple stats, way lower speed, and slightly better resistance. Resistance still isn't good enough to really be a tank, and his speed is garbage enough to get doubled. Plus if you give him DC he can't have fury. Camus' weapon gives him slightly better attack after weapon is factored in, speed means he can sometimes double but at least denies most doubles, and he gets DC built in so you can put fury on him or whatever else.

Well, you are on team feat . . . team Kat, right?
So it wouldnt be that impossible i guess?
Most players are on the fates characters, so the rest of us play against each other quite often.
I have been getting the same Tana/Lyn/and Ayra for many matches.
