Arcanist's Cephaliarch's Flail deals instant damage and Enemies are immobilized for 3 seconds,However, Sorcerer's Shattering Prison and Rune Cage only cause damage when the effect ends.
But in reality, few players are willing to give up the struggle and let the Sorcerer hold them in place.
Among all the Dark Magic lines, the most commonly used skills are Crystal Shard and Dark Exchange, but there are very few sets in the game that have buffs to cast time skills, not even Sorcerer's own passive.
If the casting time and waiting time are really Sorc's identity, then please buff this identity, because it is obviously incompatible with the current fast game environment.
Longer wait times should be rewarded more, if a player waits 2 seconds to cast an ability but gets paid the same as other instant abilities, is there any reason to convince the player to use an ability that requires a wait/cast time?
When Patch 9.1 is about to take away 10% single-target damage from Flame Staff, it is a serious blow to Sorcerer, who lacks AOE and DOT.

Magicka Sorcerer needs more tuning,
Dark Magic skill lines are severely outdated and backward
Storm Calling skill lines were supposed to be Magicka Sorcerer's class identity, but now lack uniqueness(Easily replaced by other skills)
