AP Jungler Item Fix
Really Simple:
Have more than one Jungle Item for AP junglers. One for casters, one for AA-based, and some champions like Diana and Fizz might choose between the two.
We already have two choices for AD junglers (three, actually for those crazy Cinderhulk Xin/Poppy junglers), so why not add MORE choices if they realy want AP junglers to be a viable choice.
Instead it's over a year of "We at Riot realize that you don't like this crappy jungle item, so we're removing it and replacing it with another crappy jungle item". Even if both Magus and Runeglaive existed at the same time, that would at least be some sort of choice.
AP champs are very diverse, maybe more so than AD champs. So why do we get a single crappy AP jungle item that is useless on most AP champs anyway (Why would Fiddlesticks ever buy Runeglaive? When Magus was around, Jungle Fizz went AD/Tank because Magus was pretty crap).
And finally, one of the big issues with AP junglers (if you really want to broaden the pool of remotely viable champions) is mana - they need their abilities to clear the jungle, so some regen a la Elder Lizard isn't a bad idea.
TL;DR = Riot needs to stop pretending all AP champs are the same. Diversity = CHOICE. Either they actually want AP Jungler diversity and should create some useful options, or they should stop giving the same tired "we're looking in to it, maybe some time around Season Eleven it will happen" speech every month.
