I think Shang is lower mid-tier now. His lack of damage adds up and he needs at least another good touch to win against most of the cast. Same with Cetrion, but a little higher. She requires more touches, and just about no one falls for the up boulder at a high level. (not common anyway)
I really tried to like FoN but the damage is terrible. You're talking low 20's for anything not off a D2 KB or without FB, that's pretty rough. It's a 95% zoning/5% mix variation, even with the Earthquake changes. I do like the shattering boulder KB but it's so slow and reactable, like 42 startup? AND the input is super touchy for some reason. So playing mind games with earthquake cancel and hoping to anti-air for what, 180 additional damage? Not worth it to me, they dropped the ball IMO. Building a char around KB's if their average damage isn't great is fine, but if they are tricky KB's to get then it kinda defeats the purpose and takes away value.
Lovin' D'Vorah though! Looking like my new main, along with Nightwolf right around the corner.
