irelia is seriously broken, her dueling is heavily overloaded
All irelia needs is double dorans blades to duel opponents with full items and major level advantages, throw in a trinity force and theres nothing you can do against her. Something has to be done about this monster who has no weak matchups, no weaknesses at any stage in the game, and the ability to duel any champion in the entire game.
Here's my proposed changes: Fix her E. right now if you're within 10% hp of her you'll still get stunned. Reduce her E base damage to 60 at level 1 up to 230 at rank 5(standard numbers)
Make her W only double heal against champions(a random suggestion off my head).
Reduce her base health.
