It doesn't prove whatsoever that veigar is OP, nor does it prove that veigar is not UP. I can own with Master Yi against any player, but is he considered op?
* Tier 4: Tryndamere, Malphite, Garen, Nasus, Trundle, Veigar, Sivir, Olaf, Pantheon, Heimerdinger, Yi
Explain that.
Veigar damagewise is good, could even outburst any AP champ, but if you look at his mobility, the range of his skill and his laning phase, he falls quite hard. Have you ever laned veigar against vlad, malz or even nidalee? They own veigar, which is what veigar will definitely most likely to face against, and do you know what those guys have that veigar doesn't? Sustainability, and most of them have a good ability to escape.
And please, if you're owning Chaosx please give me a replay in a ranked AT, not solo queue, even HotshotGG/Bigfatjiji lose on solo queue.
As for Elo, some people queue with substantially higher elo so you'll definitely will get queued with soemone with 1600+ elo. For example, I queue'd with my friend from 1200+ elo and I was 1400, we were faced with 1300 elo. Matchmaking system imo is fair, it can't be perfect as sometimes it will screw up but not too often to be called broken.
