(Serious Question) Has Riot Said Anything Regarding The Meta?

I've seen a lot of back and forth talk about both the short games and high burst but was wondering if Riot has actually said anything regarding their stance on the meta. The closest I've seen was a post about increasing tower armor/resistances and another on how folks in their Asian market segment who play in internet cafes prefer shorter games, but have seen nothing directly from Riot (particularly on the burst levels). Individual champions being strong/weak are one thing but I'd really expect something public by this point with the whole game getting turned on it's head. Whenever I ask after games people just say 'adapt and play burst or a tank like everyone else', but I have a hard time believing they want the game to have such huge levels of damage and such a stark dichotomy in survivability levels.

Would appreciate any info from folks who are more plugged into the development of the game.

Thanks,
