As you can see from this chart, the first chart is hardly surprising, the more you ward, the less likely it is for an enemy champion to gank, snowball and win the game. You can also see that even between diamond and challenger there's a strong discrepancy between how many pink wards are purchased.
Meanwhile, the second chart I think is more interesting...it's a correlation between ping and Elo. Does this really imply that all the Challenger ranked people live on the west coast near the Riot servers? Interesting.
Personally I think that anything under 80 is perfectly playable, and even 120 will do in a pinch. Anything more and you'll be at a disadvantage. Apparently 22 ms is the way to go in Challenger league though...
Internet + Wards = Elo?
