You probably know this, but for those that wonder, the attack speed slows are applied in the same way as attack speed increases before the attack time is calculated from base attack time. As in, all the attack speeds are additive with each other up to the maximum of 400 IAS. All attack speeds work the same way regardless of whether the game lists them as a % or a #. Which is why Viper's 105% (with Corrosive Skin) or Enchantress' 90% IAS reductions are very crippling to enemies who are below 100 IAS - but past, say, 200 IAS these effects become much less efficient. Which would be why late game Drow with some items and nobody at her melee range wouldn't really care that much about Viper Strike. Same reason why I've said Tiny with rank 3 ultimate is a rather pitiful right-clicker until he gets enough IAS to ignore the ultimate reduction.[/QUOTE]
That makes a lot more sense; but why say "80%" instead of just plain "80" if the modifiers stack additively? Why not say "reduces enemy attack speed by 80" rather than 80%?
