Nah man because that way the junglers could take ignite/exhaust/tp and have a global presence all over the map.
But with the New Jungle items (season 5) i m looking forward to play as suport with Smite, my idea is to leave the adc Solo while i (as support champion) go jungle to get those 3 stacks that allow me to upgrade the machete to the item that allows me to cast smite on champs plus slow.
Its a great idea since you will be giving to your jungle more protection from the new camps (bonuses) and help the jungler doing the buffs that spawn later :D
Whattha do yo think?
