Thinking on jungle diversity...

...I still have mixed feelings about Runeglaive. It's fine on assassin AP junglers like Diana and Nidalee, but those APs were already good in the jungle. The sheen effect and general stats just don't seem to be as good on the Mages who AREN'T succeeding in jungle currently. Does Riot just not want Mages in the jungle at all? I personally was a fan of players bold enough to bring Morgana into the jungle. Also a personal favorite of mine, Jungle Zyra has the potential to scale very well outside of the midlane, where it can be very difficult for her to deal with more popular midlaners. With good damage scaling and utility, but lacking mobility, her tradeoffs as a jungler are very clear, but it is currently completely impractical due to her early clear. Would Riot ever consider giving Zyra jungle-specific buffs like they did for Nidalee (who was nearly unheard of in jungle and was already plenty strong in lane)?
