Hear me out.

• : << Total Damage doubled against SLOWED or immobilized unit. >> Total Damage is also doubled against Attack Speed Slowed Targets ( which is why this item is so good combined with )

• Tenacity () : << Reduces the duration of any Crowd Control, Including SLOWS. >> Reduces the duration of Attack Speed Slows aswell.

So Attack Speed Slows are CLEARLY considered to be SLOWS as much as any Movement Speed Slow.

• 's R = << 100% Slow resistance >> Gives Immunity to any Attack Speed Slow aswell.

• 's R = //

So Attack Speed Slow effectiveness is CLEARLY SUPPOSED to be reduced by Slow Resistance.

THEN WHY THE HELL does Unflinching (Rune) and DOES NOT reduce Attack Speed Slows even though their description says << Reduced the effectiveness of ALL SLOWS by X >> .
