Okey here is something from my humble 3 months experience with irelia. AP scales are better but she does phsyical dmg with everything except equilibrium. So in order to be useful to 100% I think armor pen is better. Her ult for instance scales 0.5 with ap but does physical dmg. And it is really powerful if build like hybrid. I was able to make my ult (given all daggers land hit) to do 4k dmg and still be durable. Eqiulibrium is still strong regardless if you dont have m pen

Partie classée = ranked game
Partie normale = ... normal game

Recent games Garen/Akali!?!?

Time to be first post and make people realize this build needs some work. Here goes:
-looks like you're building an Akali with no escape mechanism.
-Merc treads on a champ with already ridiculous reduction to CC effects you're better getting Sorc Boots.
-Summoner spells give you no escape, heaven forbid you may need to run sometime.
You might was well drop the 2 wasted points in your offensive tree and make it a 9/21/0 build. Improved ignite is bad, and crit strike chance with no crit strike items is even worse. Throw those points into defense.
-Your build has 5 items. Assuming your're leaving a 6th for us to decide. Might as well put Catalyst the protector in there. Or Rylai's Crystal Scepter.
I'm confused as well. Not being a French speaker myself (or able to read French very well) What is the difference between Partie Classee and Partie Normale? Ranked/Unranked/Practice? Just wondering.
Other then the glaring issues I see with your build nice job in the discription.
