Not only has the NA server adapted to the EU's meta (of having ap-mid, bruiser/tank top, and ad carry + support btm), it's been quickly adapted by people in the SEA server as well. I don't only see it in Ranked games, but also in normal games.
Personally, I hate the idea of sticking to a meta-game. Yes, it wins games and it sets your team up to the point where whoever wins depends solely on skill (and coordination, ofc). It's pretty stale, imo. Having 2 ap carries face each other at mid is just like a competition of who can burst faster. Otherwise, it'd be a farmfest.
When I play, I usually go bruiser-support bot or ap top.
Playing bruiser-support bottom lane means I get to still do dmg, while not taking any farm. I usually do this with Nidalee. With my hp/5 quints and a Doran's shield, I get to harass on both the enemy support and ad carry freely. The idea in mind here is "cost effective". I farm on kills and assists (almost guaranteed every match).
Playing ap top would mean that I would have an "antimage" mid. Certain examples of antimages mid would be Talon, Kassadin, and Leblanc. Usually, I would have a Talon mid to completely destroy the enemy ap carry. Note that ap carries don't really have high armor, so a lvl 3 Rake would deal quite a blow to them. Whilst at top, the only chance of me ever winning the lane would be to kite. Otherwise, I'd just hold the lane and farm safely. Having low armor against a bruiser at top just means it'll be a farmfest for me at top.
This, usually wins the game for me. People who have no idea of how to win games, will stick super close to the meta-game. What they do not know is that there is always a counter to everything.
Also, sticking so close to a meta-game just takes away the fun in playing the game. It's just like we're all tryhards picking up pro strats just to WIN.
