same problem as all other "vel'koz is a watcher" theory, illogical choice. splitting an army and attacking from 2 fronts is tricky. it gets worse when you consider that freljord is actually literally surrounded by the most powerful enemies, in particular enemies known for utilizing weapons of mass destruction (Zhaun). to top it off conditions are worse. those 3 entered the league earlier actually. yes, even lore wise. the portal doesnt need to be opened, as seen by kogmaw who followed malzahar, without malzahar opening the void. also, you seem to confuse the void itself and the faction "the void". they are 2 different entities. kassadin and malzahar were corrupted by the void itself, although in malzahars case its likely that someone masterminded it. however, the void isnt sentient. its just a realm. and the void itself didnt really give malzahar his powers, it kind of is his power. the thing we see as "voidmagic" is just the transportation and manipulation of voidstuff, but thats a longer story.
