"Meta" has been interpreted into so many different ways throughout the community.
Today's "Meta" is more so an overall composition on how all teams are set.
It consists of the Bruiser Top, Bruiser Jungle (Keep in mind, almost all champions can jungle now), AP Caster Mid, AD Carry Bot, 0 CS Support Bot.
Some counters would be anti-mages mid, such as Kassidan or Sivir, and anyone with strong harass bot, to prevent the enemy carry from farming.
This counters the current meta, as in my interpretation.
For AOE Comps, A quick silver sash and cleanse work wonders against escaping heavy CC.
For Poke Comps, I suggest high sustain, High durability.
