Regen, Medica II's regen effect and stoneskin are overlooked for Whm, Succor and Adloq's shield as well as whispering dawn for EoS are missed on Sch. I suspect it's a lot closer than you might think!
I also think you chose to ignore where I noted that I apply stoneskin for Death Sentence? Is that not providing the same function as Adloq? (But with the slower cast time of course)
I suspect your agenda is stopping you from seeing the whole picture here, both Whm and Sch are beautifully balanced as things stand, both jobs have their own quirks over one another and we are certainly not even close to being in the same boat as War and Pld.
