I created this build plan on having a lot of CC and decent damage, but I am doubtful about the last two parts.
The other option I thought was changing Sorcerer by Psychokino (more CC) and in the end choose between Sorcerer and Necromancer.
I’m accepting suggestions.
Ps.: I took Corpse Tower in place of Flash Hoop, but I’m not sure if it was a good idea.
Psychokino has very long cds, try with wiz>cryo3>Elementalist>Chronomancer, and u will have 10 skills for CC (sleep,stone curse,freeze,slow, stop,more freeze)
I do not like Chronomancer’s skills. 
But thank you for the suggestion. 
In high levels Cryomancer has high damage?
C3 cryo will rely on snow rolling and ice wall for damage. Ice spike damage really falls off vs other classes after lv 120 since it only hits once or twice on normal mobs and only 4times on bosses. So no, since those 2 skills have long cds, your damage will be somewhat below average. Not terrible tho since ice wall is pretty damn good with a dagger (fast attacks).
Ice bolt damage really kinda sucks at lv10 and I rarely use it 
Feels like skills in cryo and ele have very low damage increments since they are mostly about multiple hits and aoe ticks, only cryo skills doesnt really hit that many times.
Ex. ice spike lv10 on boss = 4 hits 1500/hit, hail lv 10 = ~50 hits 1250/hit, prominence 10 = ~20-30hits 1600/hit w/DOT burn, all hits higher damage than ice spike. Ice wall lv10 (best cryo skill) = like 40-60 hits 800/hit.
Edit: dunno why pple advocate ele c1, it sucks. Think sorc2 might be more viable, or even sorc 1 necro 1. Also think its well known chrono is broken atm
Numbers are always excellent explanations. Thank you. 
You know somewhere or video showing the damage of the skills of Sorcerer and Necro? (Other than the skills simulator.)
