All global/semi global spells have a channel time aside from Nocturne who needs vision of the enemy and Soraka (which is just ridiculously easy to play and needs a serious rework in mechanics). So you got that right, however "allied unit" also implies you could use it on minions. That would be a mistake Imo, since every teleportation spell either works with a very visual ground targeting system, or requires a champion.
