Another WHM chicken little sees the sky falling. The sky is an AST.

Yeah, I always liked trying to use it for movement or AoE heavy phases but on all but O8S you invariably end up wanting to click it off long before it's finished =/

If SE do remove the damage down component from it, that'll make it a much more versatile and useful cooldown across pretty much any level of content <3

To be fair, as much as I dislike the sweeping buffs AST seems to be getting again, the Lightspeed change is the most needed.
Lightspeed even since 3.0 never felt like a buff, it always felt like you were losing too much to make use of it. At least now it'll feel like an actual buff..
