She isn't worth learning... Her kit is the problem, like Akali.
They made her entire kit based on reflex. Or you are someone with very high reflex who can press 3 times Q in less than 1s while dashing at low hp minions or you can't play her.
Don't watch pro plays of Irelia, it's not realistic at all, nobody is able to play Irelia like that. These guys are pressing E and dashing so fast that you don't know what they are doing.
The champ turned into a "press the button the faster" because of pros so Riot balanced Irelia around that. Unless you are Terminator or someone with very very very very good reflexes and with a superbrain, she isn't playable.
Or you have a 2nd option : Play vs someone who is very bad and you may win. Also the guy have to be a ranged champ because Irelia can't win vs melee champs.
I love Irelia but i don't like to play her because she has turned into a pure "reflex" champ. And if you miss something, you are dead.
When you see people dashing 5 times in less than 1,25s because they pressed Q 5 times on low minions, how can you do that ? I can't even do that. I need time to place skillshoots, to aim properly... With Irelia you don't have time, you must do things in "rapidly mode".
People don't even use the E range (for example using E then dash on a minion then place the other part of the E). They try to use the E the smallest size because it's faster. Everthing is about rapidity.
The W is a physical dmg reduction that can last 3s. But nobody is using this spell to 3s to deal the max dmg. Everyone is like "pressing W for 0,25s to block a big AA or a spell" then dash or attack.
I don't like it, it's too mcuh stressful and annoying. This kind of gameplay feel like you don't even have the right to make mistakes. When people can play Nasus, only farm and get stacks and later 3 shooting and you are playing Irelia, i feel bad.
But you can't buff her because it's only about reflexes. If you buff her, it's won't change a big thing in Bronze or Silver. But people who are maining her are going to be extremely oppresive because when she is good played, she don't have counters.
The only counter to Irelia is to make her weak so she can only fight vs ranged champ and be played correctly by 0,1% of LOL community. That prove how bad her kit is.
