I'd pay premium for SE to make an entire raid series where both healers are needed in endgame content, tank and dps healing is still welcomed on top of that, ilvl can't cheese all the healing (it still has some teeth after gear), SGE and SCH can't handle it because its not entirely mitigation based but also healing based with heal checks that aren't just "heal to full to prevent doom", have debuffs you want to clense and not just HoT over, isn't just a Dance Dance Revolution fight - it has tonze more unavoidable raid wide damage, off tank responsibilites, AND they don't nerf it what so ever.
They don't have the spine.
Edit: I'll even add that they keep doing so for all future raid series and don't back track next expansion.
