SCH in 2.0 ARR had significantly more DPS spells/abilities than it currently has in Shadowbringers.

SCH at start of 2.0 ARR
- Ruin, Ruin II for nukes.
- Energy Drain for MP and nuke.
- Bio, Bio II, Miasma, Miasma II, Aero, and Thunder for DoTs.
- Bane and Blizzard II for AoE.
- 100 percent uptime for Shadowflare.
- Strong Fairy potency.

SCH at start of 5.0 Shadowbringers
- Broil, Biolysis, Art of War
- No Energy Drain
- Nerfed Fairy potency.

There is a reason why healers say SCH has been completely gutted and shell of itself. The dev team are extremely incompetent.
