As someone who uses Freezing crystal rose a lot.
Its not that opressive most of the time at all in my opinion. I am pretty much with Senna here, that we have a lot more terrible and Momentum effective ways in this game, gain air/winged serpet as a 1M 8 tile+airborne movement as example is a lot more opressive.

So in my experinces Crystal rose is :
-It needs an infliciton check, while as Ice user you usually have that decently high through skill alone, I run often into people I can't freeze.
-It's really good when you manage to get it off in a Teamfight, to allow a teammate one deceicive hit, this is in my opinion it's stronger point.
-Thanks to the relatively short range, it's actually often put you inside of the enemies attack range, more often than not I just get counter attacked without them even bothering to struggle out of it, knowing I break it eventually for them.
-It a good tool to get one attack in, against extreme dodgers and Cobra users, but thats hardly oppressive as you can do that only once every so often and while being in the right range for it being worth it.

Over all, it's certainly a very nice and good effect, but I still find Lightning crit and fire outmatch it in terms of duels. It shines most it Team fights, which I like.

Just my opinion and experinces with it, I do not think it's too strong with the recent changes to it. Wind and Earth Crystal rose could need a tiny addon though as those two clearly fell behind.
