What if there was an item that decreases how long a certain effect stays on you (3-hit procs, etc)?
Things like: 3-hit passives, other passives (Darius' for example) Debuffs Masteries that deal something over time (DFT, Fervor stacks, etc) Item stacks (Black Cleaver, etc)
The general gist of the item would be:
UNIQUE - (name here): Reduces duration of enemy-applied effects by X%.
10% or so? Numbers are all up for discussion.
How would that affect current meta and balance?
