SoO nearly half the fights it has solid use on:
Immerseus - Sha Bolt, Swirl, Seeping Sha, Swelling Corruption, Erupting Sha, Sha Pool
The Fallen Protectors - Basically all of Sun Tenderheart, Corrupted Brew
Norushen - Manifestion's AoE, Essence of Corruptions' Nuke
Sha of Pride - Litterally everything, Especially good for Unstable Corruption and Swelling Pride
Malkorok - Pulsing AoE, Puddles, and Breath
Garrosh Hellscream - Desecrate, Whirling Corruption, Annihilate, Malace
Galakras, Iron Juggernaut, Dark Shaman, Spoils (Mostly), Thok, Seigecrafter and Klaxxi - Don't have Shadow / Holy damage, but with the glyph in WoD have mechanics that you could absorb.
ToT was a little less, mainly due the 'lightning theme':
Council of Elders - Dark Power, Soul Fragment, Twisted Fate
Durumu - Dark Parasite, Linger Gaze,
Twin Consorts - Lurkers in the Night
Again here, with the WoD glyph it'll be useful on almost every fight
Most people most likely just ignore it in almost all those cases because it cost a GCD which is just such a hugeeee damage losss, however in cases where your healers are behind or when you are under-geared it can easily save you from death.
TL : DR - I would be really upset if it was removed, and I'm glad they are adding a glyph for all schools
