Then no deal. All you've asked for (touch attacks, teleport, plane shifting, free IHS) warrants a strong counter-balance point. And it also needs to be something original that hasn't been done for
The current Fantasy Heaven full combo isn't easy to pull off yes, but it isn't supposed to in the first place, and meanwhile, you do get the stacking sacred bonus to a bunch of stuff. 9th level stances aren't supposed to be something you pull off for mook cleaning and utility, it's supposed to be something you pull off only against the toughest opponents. Aka when you're already wanting to cry.
It would make me want to cry
from having to constantly adjust half a dozen different things. AC, Will Saves, Save DC's,
attack bonuses, everything derived from Wisdom from the tactical feats, skill checks...
Every round.'It needs to be something that hasn't been done before' is just making this more intentionally cumbersome.
My concern with the current Fantasy Heaven is that it's... basically useless. You get a mounting bonus, yeah, but you need to find an enemy that you can hit seven times consecutively at a minimum without its dying. Since you only have three attacks a round (this not being very TWF-y), that's three rounds if every attack hit, which seems a bit long to maybe get a 100 damage area attack (seriously, three rounds to MAYBE do a lot of damage, by which point there's unlikely to be enough left to even justify it?). Three rounds of
not using basically any of the other strikes from this entire school, without any of the defensive or practical bonuses from the lower stances.
