I went ahead and fought 3 NS squads yesterday and won all 3, only 1 of them was a close call against an almost perma stealthed acolyte. The other 2 were draws against Phoenix which pretty much solidified my resolve to NEVER fight them again lol!
I think Sabine needs a bump in shard locations, if she was more accessible more people would enjoy phoenix farming rather than the tedious job it feels like now. I know most swap out Ezra for Sabine but in cases like the stalemate arena I'd swap out a tank, it's just a little extra damage needed to beat other phoenix.
