Sorcerer is a mess now due to the unclear goals of each skill line, passives and active abilities. It's a relic of base game, and likely an original concept of Sorcerers being the "magic dps" class, and not healers or tanks.
The skill moves you did for Nightblade (moving Blur, Concealed Weapon, etc)? Sorcerer needs it bad. Really bad.
The only ability that they could conceivably call a spammable is in Dark Magic, with literally NO damage passives belonging to that tree.
Daedric Summoning suffers similarly. The passives are largely tank focused, albeit with some cross utility. However, the pets contained within the skill line have literally been one of the few things keeping their damage competitive to other classes. And another staple of their damage, Daedric Curse, is contained within that skill line...
Storm Calling has DPS focused passives at least, but with the exception of Hurricane, the least used damage options on the class, especially with the addition of Subclassing.
The class honestly needs more moves than you gave Nightblade, in a big way. And many of the active abilities need huge buffs to even be competitive to anything other classes offer.
