@ChillBEASTOYTactical and ultimate seems like the same skill just scaled up.
I've suggested something similar before so I'm not against the idea of an ice-themed Legend, just maybe some tweaks here and there to make things more interesting.
Some thoughts:
Ice grenade could potentially encapsule a player in ice, offering a small amount of armor, but slowing them. Making it niche, but useful in some defencive scenarios. This could also give team mates the "cannot be detected by scans" passive for as long as they are chilled.
If an ice grenade doesn't hit anyone, it leaves an ice pillar behind. The pillar has XX health but will shatter if shot, exploding with ice shrapnel and a minor slow down AoE.
Throwing an ice grenade on a door encases it in ice (can not be opened by anyone unless destroyed)
Blizzard could create lasting destructable randomized cover (snow/ice) after being used. Ice grenade thrown on that cover could empower it.
Using blizzard in a slope could make the ground slick. Or it could create a layer of snow that you could throw a grenade on to make it come loose in an avalanche.
etc. etc....
Skills working togeteher and having interesting effects gives them more value, so try expanding on it.
