Any melee or caster hates being kited, especially when its by a hunter when you can't LoS and have a constant 50% snare being shot at and kited around. I find it annoying as a rogue, Evasion helps, but due to RNG that 25% miss isn't going to occur often, I could sprint over the Frost trap, but its no good if the hunter just disengages over the trap again and kite me around.
My solution is to make Frost trap into something like CoI but instead an AoE type that lasts for 30 seconds on the floor, and allows you to regain speed every (X) amount of time. This also means hunters would need to door more rather than just kite around, which means it takes more skill.
