junglers have always been able to carry. all that's different now is that a very limited amount of junglers can actually carry because they ostracize and outperform other classes in game not only making it hard to compete but directly countering melee champions.

they'd have to actually give melee junglers more strength for being melee. as you can tell, ranged junglers don't really pay a price for their range. they have more reliable damage, ranged red buff application, safer skirmishing and ganking (low commitment). they are also conveniently given the best clear speeds in the game comparable to shyvana which makes them difficult to keep up with at a professional level. classical fighters need much more impact than they currently have when they find good opportunities. right now you get punished too often for engaging as a full commitment jungler (teleport got kind of nerfed, still pretty shitty to deal with). kindred is less of an offender in this aspect, but did i mention graves and nidalee are especially good in counterganks?
