I mean, watch any Chinese high elo stream or tournament. He's everywhere there.
This is key - conventional wisdom is often proven wrong (a lot of the old EU meta transferred to NA after a major tournament), especially when other regions are showing the power of different characters. It's easy for people to assume the entire balance is only based on what's working or flavorful now, but there's surprises regularly that shake things up.
Ezreal's somewhere in there for NA - he's not worse than AD carries, he offers better skirmish and harass than other carries.
I want some hard evidence or *proof*
Not you rambling on saying how he's good in China. (I'm not trying to insult you)
Where am I suppose to find Chinese High Elo streams? Where can I see these tournaments? Do you expect any of us to have a single clue on how to find them using an American Google with english words?
