Personally I'll say Time works well with Ice. The auras in both are the same size and you get both before 10. The only problem this is a low DPS and a overall hot character end wise. Even with the IO's I normally used to stop the end drain on other character this one still feels the heat when I have to start clearing rooms without much downtime. Besides that Ice/Time is still great because you can just stand in most mobs and watch them get snared while the team kills them. Personally from what I played you'll like having Glacier in this setup because you're mainly gonna be in melee range basically hugging a tank. Don't get Shiver, Flash Freeze or Jack Frost. Yes don't get Jack it isn't worth the investment if you're gonna group put more investment into time. Now have 4 holds 3 of them come up pretty fast, Glacier is your slow one. A lot of snares, good healing, buffs/debuffs the problem is one thing you have to get use to you don't do damage. You're basically in the room to make sure the enemy has a very bad day. Then for late game either go Ice or Leviathan since Hibernate is gonna be your friend because they'll will be times when another mob or two sees you and start shooting you in group play. Just pop Hibernate and let the party catch up.
