Drain's tether range has been severely reduced. Riot should really include these kinds of game breaking changes in their patch notes. Fiddlesticks now loses 3-4 ticks of drain, possibly more, in his ganks. This is especially bad because of how fear works now. Soon, we won't see Fiddlesticks being played at all anymore.

FiddlesticksのDrain(W)の吸収可能範囲が大幅に減少していることが海外のフォーラムで話題になっています。
これに対してRiot GamesのRiotPwyff氏は「Live gameplay Teamの意図しない変更(バグ)であり、現在調査中です。深くお詫び申し上げます」とTwitter上で発言しています。
