tripple support.
well this was always going to be interesting, the builds are incomplete in some places, and i disagree with the ethic in some of the builds but the concept is...
well i admit in a highly skilled team it COULD work.
but most likely it won't.
Make no mistake this entire build hinges on poppy and ashe. they, with the partial exception of lux, are the only ones that can do ANY damage, and this just makes you all too easy to focus. Poppy is an excellent choice since she can pretty much take on anything and everything and come out alive and with a kill.
Secondly as someone pointed out your Janna build sucks. it's fine to have a walking aura-*****, but that's all she does. Janna needs SOME AP in order to be effective, every single one of her abilities scale very well off AP. a single rabbadons would make a huge difference. at the moment she's kind of off-tanky, but just provides auras and a mediocre heal/shield. at least she still has her knock and slow.
Honestly i'd swap Taric for amumu. he may not be able to heal, but he's so much better at iniating/CC with bandage toss/curse of the sad mummy.

CC on this is just so damn good. good build. though you could improve the janna build. its kinda bad.. but good anyway. :D

Quality guide. The teamfights with this build are just ******ed with the amount of control this has.
