Frozen getting Aftermath Immunity over Crystal Rose (which is only a recent addition and has yet to be properly combed) is, beyond being a kneejerk response, overkill for only one skill that can currently throw out Frozen a little too easily. Reserve that kind of judgment for when/if Frozen shows up on more skills, especially when it's for a skill that could get its Frozen effect patched out.

Even with that being said, the only thing that really makes Frozen as busted as it is, is the Immobilize effect add-on. Make it act like Slow at lower LVs and you lose the lockdown that Kameron suggested and everything should be satisfied, though I'd still take it off of the base effect first.

The frozen immunity is more so for in general. Frigid arrow spammers (although annorum has a CD anyway), ice tyrants, etc. anything that can inflict frozen it would just make it so you cant sit there expecting to keep people frozen. Locking a bunch of classes in place that rely on basic movement only to start setting up is a knee-jerk itself. If you don't have blink, cleanse potion, or a class that helps with removing debuffs you're pretty much a sitting duck. Being able to move is a big deal.
