that long range thing of his, won't that suck for enemy jungler because swain can pressure camp lasthitting with it thus forcing smites and stuff.. :/
like a xerath q doesn't add pressure because he either steal or don't steal, no counterplay. but this swain thing will force them to use smite on, for example, early blue (because detonation is delayed) and swain doesn't even have to give up any resources by having to walk so close.
just my thought
edit: Targeted spells now draw minion aggro.. wowe
