Hey there! When I first heard about the game, a telekinetic time controlling mage sounded really cool to me and I wanted to make a similar CC orientated build (more of the offensive).
As far as the current meta goes, it seems skipping chrono C3 as a supporter is an outright bad decision (or seen that way) and so I’d recommend you aim for Chronomancer C3 if this is the character you want to play upon release and enjoy doing so.
Cryo-Psycho C2 is probably considered an odd combination of ranks for a supporter, although it’s safe to assume CC classes all work well with each other. IMO, if you get a Hummingbird gem to raise your Ice Wall to Lvl 6 you should be able to pull some pretty cool stuff with your psycho skills.
As far as your build I think it looks fine although id suggest you use points from Magnetic Force (you only get damage out of levelling it, and you won’t want it for damage) into Raise (!!), Teleport & maybe a few in Swap;
