I have over 300 games as Irelia in ranked (200 wins approx) in Gold 4. So I have a lot of experience playing her and she only struggles against Jax ( who doesn't) and Olaf. but even they are no match if you have the know-how. This is my second build so don't be too harsh but room for improvement is the main thing which is there.

Lets keep it short.

Q - Her Q, this move scales 100% off her AD, unlike most other champs if you take the right runes this will be enough damage early.


W - Her next move, her W is very useful and if you're more confident with Irelia starting with a Dorans Blade is good as it scales with the passive. She deals true damage, this is good agaisnt other tanky bruisers in top such as Garen and Wukong.

E - This must be one of the best fight changing moves in the game. If you are chasing someone lower hp% than you its becomes a slow, need an escape, when your going low? Works as a stun when your opponent has higher hp%.

R - Her ult is good at taking at those low hp enemies who are scrambling away from your might power. Don't let them get away!

Damage is important early game and so is tankiness, with the right mixture you are unstoppable.
Because of hybrid marks and magic resist and armour glyphs and marks the balance is there. The items Tie up late game for the tankiness which starts to lack. There's not much more there is to say about this.
