Can someone please tell me what exactly is going on in the lore as of 2016? I am having people say that champs are not cannon, and that summoners are no longer a thing and the same with the "League of Legends". can someone please tell me what is going on?
Man you are really out of date. The League was written out of the League of Legends like 2 years ago. After that there was like a year where there was no lore at all. Then Riot started going through different locations and updating their lores piece by piece.
Here's the big ones:
Bilgewater event Gangplank no longer runs Bilgewater, and he lost his arm. Miss Fortune now runs Bilgewater, we're not sure how good of a job she's doing. TF and Graves have buried the hatchet.
Bilgewater event 2, now with more monsters Miss Fortune defends Bilgewater during the Harrowing Olaf now wanders around the world fighting monsters and trying to die Thresh and Lucian fought for a second, Thresh tells Lu that his wife is stuck inside the lantern
Targon Taric is now a Targonian champion All the Targonian champions are now possessed to varying degrees by space aliens that have a galactic empire because they captured a star dragon god (Sol) millennia ago. Leona sorta was evil for a second, then was possessed and now she's good-ish Diana still killed the elders, but now feels really bad about it. Sol is coming to Runeterra and is willing to destroy the planet to get free, he doesn't like the targonians all that much. Taric's space alien actually seems like a decent enough dude who just lets Taric do his thing.
Shurima Nasus and Renekton are no longer aliens, they're Ascended beings from Shurima (dudes who got a magic power up hundreds/thousands of years ago) So are Azir and Xerath Taliyah and Sivir are also there Sivir is a descendant of former emperor Azir When Sivir and Cassiopeia went to grave rob in Shurima, Cass got turned into a snake lady, Azir woke up, Xerath and Renekton were freed from their prison Azir rises up a Sun Disk Sivir meets up with Taliyah and Nasus Xerath does a lot of magic stuff, ends up fighting Nasus and kicking his ass while Sivir and Taliyah run away Nasus says to stop Xerath he's going to go find his brother
That's pretty much it, besides new champion bios.
A couple years ago Riot announced officially that the Institute of war no longer existed and anything having to do with the Institute and Summoners (as they were then, there have been hints that there are "summoners" but in a different purpose in Runeterra) was retconned... A lot of older champs like 
who's lore's cant exist without the IoW are kinda in a grey spot. They exist but as of now we dont know how or what purpose they have in Runeterra now.
TL:DR Champions exist but certain ones have unknown purposes at the moment. There is no more "League of Legends" or "Istitute of War" in Runeterra
