I wouldn't say that Fear is the only skill that has these kinds of problems. I don't know if you have encountered people who shield charge and root you, but that is a lot of the times impossible to break free from, since for some reason knockback + root is broken like that, this is also a problem that has been in the game since launch and has been reported many many times over and still has not been fixed.

I think whichever class you fight, you will always find something that you are having trouble with. But this is the first time in a very long while that Magicka Nightblade is really viable again, and to be honest all their moves are quite easy to counter if you know how to, though I will say that Fear needs to be changed. It should have a bigger radius, but to balance this buff they should make it similar to all the other unblockable CCs in the sense that damage will break it. If you have played a nightblade and have a constantly high ping you will know that it is very hard to even hit people with Fear unless you are literally right on top of them.

Lol just as I said, when cloak gets nerfed they'll jump onto fear.

This is an issue with CC break, NOT just fear.

Happens with Petrify, wreckingblow, leap, crystal fragments.

Yes, yes it is.
