Lux's ult

Why?

It isn't a channel.

Just because you are getting rekt by lux ult doesn't mean Riot needs to nerf it.

death is the only true disruption.

it is coded as a cast time and not a channel and it has a .5 second cast time

same for ulti which has a 1 second cast time

spears also have a cast time long enough to notice this after the cast time got doubled in patch 5.15

and is also why arcane shift and rocket jump cant be interrupted. (although at least for trist you can cc her after she has left the ground, just not while on the ground)

none of these skills can be interupted.
