Hi there! Im playing with wizz1 > cryo 1> Kino 3 now.
The full Cryokino is totally PvP guided. If you’re thinking about PvE maybe you should go for another build, imo. but If you insist, I believe 1:1 int/con should work just fine, very well balanced. If you’re going to CC in pvp, then go full con.
Just be careful there, if you want to focus on PvE and defeating bosses, you’re gonna lack power for a good dps, so maybe you could go one rank rune caster for the Ice wall + PP combo or take off one rank of cryo to go warlock 1 - sage 1. If you wanna go for PvP, then this build still works fine, even with the gravity pole nerf.
hope this helps!
