This is all subjective apart from maybe Arteezy.
Basing so much off of stats is really unfair to the Russian carries that tend to play a more active part in the early game and play things like Silencer, Pugna or Lina rather than AM, Naga, or SF.
Yea I agree, that's the sense I tried to convey that it was the opinion of GosuGamers in the title, perhaps I'll fix it if I can think of a way to word it. To be honest I disagree with most of the ranking, except Arteezy, but I thought it was interesting to see where others think they stand.
I think the fact that it's a GosuGamers article makes it pretty clear it's just their opinion :D. Your title is fine.
