I agree with the last statement. There is no purpose for smite unless it is necessary to clear the jungle becuase without the items, it doesnt do anything outside of jungle monsters, and those items are geared toward what junglers need.
The only reasonable changes here, i think, are remove smite and make the jungle easy, or to make things more fair and be the same across the board, make other role specific items attached to crucial summoner spells, and make them stronger and more specialized.
for example, beef up the support items and link them with a support spell like exhaust. I know people are already not liking this, but smite is the only item specific summoner spell and its actually not fair for junglers to be forced to take smite and only have 1 flexible summoner spell, which is pretty much just flash if were being honest 90%+ of the time its flash and something else so junglers really dont get a flex summoner they are pretty much locked in to smite / flash.
to be clear im ok with the way things are and im not complaining about anything. All im saying is that if there is going to be a change in the flavor of smiteless junglers it needs to be an "All-In" approach one way or the other.
