Mathematically speaking... warding hurts your team
Take a look at the top 3 teams in NA LCS: imt, clg, tsm
in week 6, the top 3 wpm (wards per minute) supports played for: dig, c9, imt
for the split they are: nv, c9, imt
Thus warding more than your opponent support means you only have a 33% chance of being top of the class since imt is the only team to make top of the class AND top of class for wards per minute. STOP WARDING PEOPLE.
Gotta love the power of numerical manipulation to support faulty claims. But seriously... please do ward.[slayer-jinx-wink]
