Well,
Now that damage has been reduced, fusion has been nerfed, and decap / assassinate "etc" are going back to normal... I BEG you to leave Ice Comet / Nova as it currently stands.
Right now, Ice Comet / Nova will hit for around 30-40% of a persons life.... on a crit, vs legendary / fabled gear, then its down for 45 seconds (40 seconds with AApts). Now, if you reduce the damage output of the spell, you are essentially giving us the fury spell Bolt of Storms MK2 tbh =(
Leave the spell how it is, and simply scale it down with everything else, but do NOT nerf it like Fusion has been... its our bread and butter, and our class defining spell, like assassinate and decap etc, there is no need to reduce it, as currently it doesnt hit amazingly high anyway.
Post here and support Ice Comet / Nova NOT being nerfed tbh.
