didn't I mention this like a month ago?

I apologize for their title if it's any infraction, but the idea I mentioned was a roaming support jungler aiding top(blitzcrank, bard, etc).
Though this seems to be a premade, it's the same concept only improved upon with now a marksman in top
I've also mentioned double marksmen before(though that was for a support marksman back before miss fortune was a thing)
I feel bad for the poor garen in this video XD
really, the concept could probably be applied to anything with strong crowd control and lane pressure
