User blog comment:Mineko Charat Lucky/Your Champion Abilities Now Refresh on Kills and Assists Like Katarina/@comment-4834593-20130219191201/@comment-204.108.65.36-20130219202738

Straight from the post "What sort of team composition would be OP when all their abilities refresh on kills and assists?" ALL their abilities refresh on kills and assists. OP mentioned Grave's Collateral Damage, Trundle's Pillar of Filth, Cho'gath's Feast and Lux's Final Spark (or Finales Funkeln if you prefer), which all have cooldowns longer than 15 seconds (one depending on level). So I'm sure OP didn't mean a 15 second reduce, but rather a full refresh on all abilities. So it is just another one of the hundreds you claim have been done.
