very good points but some how it allowed me to put Dangerous Game without selecting Executioner .
And this guide is for the carry type it means if you went 3-0 or + before team fights start means the team already depending on you but yes you are right i will make it clear in the guide thank you so much for the feed back Aklemony.

Your ability sequence is pretty messed up as you generally skill up your ultimate at level 6/11/16 and max abilities at 9/13/18.
You cannot select Dangerous Game without slecting Executioner .
Last Whisper is an option on Irelia but most of the time not recommendable. You're better off building another defensive item such as Frozen Heart, Thornmail, Banshee's Veil or Guardian Angel depending on the game.
Greater Quintessence of Attack Speed + Greater Mark of Attack Damage is an even better combination.

[[Irelia]] is another coding you can use. Try to consider the upper and lower case and more formal language.
