Pretty simple mix match of Skill sets here some minor adjustments can be made based on playstyle but easy to use. CC ambush attacks are vicious used on you but you can get one break you can still win in some cases.
My Initial rotation looks like this
Freeze

+
Then trip
+

At this point you can either go with the following combos
1- + for high damage lock down and if freeze is still on adds dmg bonus
or
2.+ for quick dmg if you need to get a pop defensive buffs.

pretty much locks down the target or targets in for Meteor strike. if target is still frozen you can finish off with
you can also get out for a quik heal and jump right back in with combo followed by and

if targets are still alive at this point i buff and combo followed by

My main focus though is to trap and meteor. and are the most effective ways to get freezing step on your target.
i have traded out
for for ranged clases or when running around solo with no cc in group for ambush attacks.
