Why not make 2 AP jungle items?
Rito has always been in a state of flux around the AP jungle item, just like it has with devourer/madreds/feral flare whatever it is. The last iteration (runeglaive) gave the option of using a high amount of untraditional melee ap assassins (fizz, akali, ekko) as junglers with good success. If we look at the traditional ap jungler (all 2 of them) it was pretty frigging bad on fiddlesticks (who's always had split opinions about whether to even BUY a jungle item or just rush zhonyas) and it was good on Elise. The new item being introduced basically makes all the new runeglaive champions bad in the jungle, Elise keeps on being fine (as always), Fiddle might actually look at the recommended items again, and ehh... Jungle Karma is better now boyz? She is sincerely the only champion I could find other than fiddle where the new item would be a good thing for her if you went into the jungle with her. (remember diamondprox back in season 3? guess he's happy). So why don't riot not just make 2 AP enchants, one for traditional mages in the jungle, and another one for assassins. They have one for spellcasting and aa focused ad's, so why not 2 for ap's?
is an awful duelist? You need a Doctor, severely.
