No different to getting shutdown by blade barrage or nova bomb is it?

In that case you could say it's like get shot with Felwinters. The difference is it's considerably easier to get a freezing ability back than it is a whole super. I would also like to point out that where Nova Bomb and Blade Barrage are concerned, their super energy is only drained once they actually unleash their respective super, unlike Thundercrash where you are the super. Roaming supers are also not suppressed by a freezing grenade, they simply need to free themselves in an instant and then continue on their way. So I would make a point of saying there is a considerable distance.

Oh I thought you mean by stasis supers not by abilities, I didn't actually know they could do that. So what stasis abilities can actually hit a thundercrash? Grenades would rarely freeze them when they're in the air right? There's the warlock melee but that would be hard to pull off
