I and many other people would like to see the following skills to be added in multicast list :
Lucifer : Scorched Earth
Sand King : Sand Storm ( but it must be rebalanced - lower the duration from 80 seconds to 30 )
Spectre ultimate
Sniper Ultame
Ember Spirit : Flame Guard
Atropos Ultimate
Pudge Ultimate
Multicast is the top skill that makes the Lod so deam fun and interesting , so it would be good to be stackable with those skills that i mentioned .
