1. I am fine with Sacred Soil tbh. I would rather use my mp spamming miasma 2 instead of sacred soil. And it is only used in ultima attacks mostly. I barely use it in dungeons, unless tank is bad.
2. Deployment tactics 60 sec will make sch op, deploying crit shield every min is insane.
3. Whispering dawn lasts 30 sec. Do you want regen all the time? Then what's the point of fey union or for example, whm regen?
4. Again 6 stacks is too much. 3 stacks in 45 sec is already enough, i agree dissipation needs a poke though.
5. Again 120 potency dmg is higher than smn tribind. We already have an aoe miasma with a nice potency and dots. Silent dusk needs rework but not like that.
6. Passive ability? %5 would be nice but it is still a constant buff to party every min that lasts 30 sec.

It appears you want sch to fly to the moon. Tbh, i am happy with the sch right now except for couple of things but its heals aren't a problem.
