User blog comment:BlitzerRyuusei/Rating supports by their poke, sustain, and burst/@comment-5266525-20131010095219

Burst is a poor statistic to rate supports by and I strongly disagree with a lot of the ratings there anyway. Thresh does not have burst on par with Leona or even Taric and yet he's tied for 1st place, and neither is Alistar very high burst at all.
