I think the "meta" is often a dumb concept
This is just an opinion i have based on both my games, and watching competitive League.
From what i can understand the "meta" changes a lot based on how the pro teams want to play the map, and what kind of team composition they want to run and find the most effective. For example right now from what i see so many teams run the heavy engage tf comp with Jarvan Sivir and Annie and Gnar. It works really good and that creates a "meta game" when many other pros and people uses those champs and style.
So this is pretty clear to udnerstand and there is nothign wrong about it.
What i don't understand is why some champions who are not buffed or nerfed in long time just become suddently OP as fuck when they did the same exact thing in ages. Examples: Janna was never ever used in pro play, then suddently at world 2014 they said "well this champ disengage wonders and lanes good against most others, this is OP". Why? i mean Janna is the same as always and did the exact same thing to my knowledge before world 2014. She always had that disengage role so why she is now op? Lissandra same story, never ever play (only a EU played her but in season 3) never used for long time, exact same role and kit, can engage and lock down a team. But only now she seems to be meta and viable. I think that is pretty dumb.
That's why i love pro players like the Unicorns of Love, who actually every now and then break the meta apart and wins with that. Jungle Tf, Poppy top, Swain, they show that if you use some champions with a brain the "meta" is nothing. Really crumbles apart.
So i would like to hear from you what you guys think about the state of the meta, and if you agree with me
