Sleet Storm and its morphs should reduce the movement speed of the caster the same amount as the ability does to those snared by the ability's AoE.
Beyond this, the Warden should be slowed down for the duration of the ability's AoE until it ends.
These are snow, sleet, frost abilities, therefore they should reduce the caster's speed while the caster walks around the entire time this AoE is blowing around them.
Right now in Cyrodiil you have packs of Wardens running around at speed cap all spamming this ability and its morphs while each one of them is also running Rush of Agony and other pull-ins which don't trigger any CC immunity on those pulled in. It's ridiculous.
So please make this ability more realistic. The caster's movement speed is reduced for the duration of the AoE by the same amount as the AoE snare does to all those affected.
And while you're at it ZOS, fix Rush of Agony's range check and give those pulled in by it the CC immunity they deserve after being pulled in.
But yeah ZOS...Cloak is the problem.
