Riot, I think you could simplify jungle by removing the jungler items.

Sure they might allow a few champs to work in jungle who would otherwise not be able to jungle but all of the jungle items generally have weaker elements of other non jungler items. Runic Echoes= Luden's echo, Warior=ghostblade/death's dance, cinderhulk=sunfirecape, bloodrazor=BotRK. If you are jungling and get a jungle starting item you are stuck with one of these 4 options. This was not the case when I started playing.

If jungler items were removed and a "hand of midas" like effect were added to smite (if exp gains are not high enough for junglers and non junglers taking camps was a problem) and perhaps restore 15% of missing health and mana or soemthing to that effect (likely abuse case brought up so moving this to the side). I seriously do not see how the game would be that negatively effected. Yes I am aware that a few changes to minor camps would likely have to happen but junglers would still have reason to be played especially in this age of elemental dragons.

And a shyvana could rush a bilgewater cutlass if she wanted stronger ganks. There are items for that kind of thing in the game outside of smite enchantments. Need clear speed? By a tiamat. Build what you need for your situation instead of what the jungler items are offering you,

I am suggesting if the active of "hand of midas" and nothing else were applied to summoner spell: Smite to some way, jungle items would likely have no real need to be in the game given they are weaker compared to similar items.

Remember only something like the active is being suggested. With the 2 smite charge system you would have no excuse in why you can not smite fairly often.
