As someone who mains casters (and plays mostly r10 questing) let me recommend the following:
0) Lowering damage on Draconic mantle to bring it in line with the Primal mantle.
1) Lowering the damage on Ruin and Gruin
2) Lowering Eburst scaling as well as scaling on AOE spells.
3) The reduction of crit chance bonuses. (E.x., from Pomura's augment, the exceptional bonuses, etc)
4) The reduction of crit damage bonuses. (E.x., from Dino Bone)
5) Nerfing the crit chance on frozen wanderer filigree bonus. Ice is already the best element for sorcs and druids, no need to help it even more.
The floor for damage casters is already too high. By trimming the top you aren't going to change much. The whole archetype is overperforming; however, it is mostly overperforming on Sorc and Druid. Warlock, Wizard, Artificer, and Bard are all not overperforming in the damage department.
Sorc could use a 30% nerf, but not in a way that affects other casters.
Druid about 20%.
Alchemist damage is really not that impressive IMO. Blightcaster is also not overperforming so it getting hit with a nerf is not good.
There are actually two separate problems:
1) AOE trash clear on r1 is too good.
2) Single target damage at cap for your **average r10 pug** is too much.
