[GAMEPLAY BUG] THRESH RUNNANS BUG
when playing on-hit thresh, after finishing (in order) berserkers greaves, blade of the ruined king, frozen mallet, wit's end, and then runnan's hurricane, your attack speed suddenly drops dramatically while attacking more than one unit (wolves for example) but as soon as all surrounding units are gone, your isolated target starts getting hit at your full attack speed. this was consistent with every situation, minions, champions, anything where your passive bolts need to fire. this is with standard AD masteries and flat damage AD marks and quints, with armour and MR glyphs and seals. it must be pointed out that prior to runnans your attack speed and animations remain the same, and after selling it the animations were again in sync with the listed ASS, but while having it the bolts themselves seem to break your attack animation so you are attacking slower than your listed AS
