Some misunderstanding about champions like Irelia
###Introduction
We can all say that a champion like Irelia is really strong and has always seen as a dominant pick, thus why people always are asking to give Irelia a more meaningfull nerf then that -5 to Movement Speed.
What I feel like some people are misunderstanding about Irelia in particular is that she's not actually broken, or she wouldn't be atleast if it wasn't for the follwing things...
###Trinity Force
I'm surprised that no one, absolutely no one is talking how strong this item is, in almost every way.
- Great/meaningfull/useful item stats
- Great first item choice regardless of it's high price
- Has a good item path making the investment not risky
- Another item that offers possibly the most damage in the game (aside from Deathcap Stat & Passive, etc...)
- Offers almost every stat that there is
###Q interaction with Trinity Force Sheen Passive
Irelia is strong because she can continuesly apply the free Trinity Force Sheen Damage alongside her base Q damage (which isn't really that high, 5 - 85 [60% AD]) on marked targets with her Q for free.
The Trinity Force Sheen Passive gives her atleast 150-200 or more damage on every proc, and add up her Q damage making it basically do 235-285 or more damage on every Q use.
###Level 2 Powerspike
Again not an issue with her directly, but this time it's a rune. Conqueror.
Not only does this Rune give her an advantage in the bonus AD she gets from it but it also transfers 20% of her dealt damage into True Damage.
###With Conqueror...
- 20% of her total damage dealt ignores base defenses, making sure you can't trade or fight her when ever it's up.
- She can continuesly refresh this effect because she's a melee champion, making her always a threat.
- Has bonus AD, basically giving her an another advantage to making sure you again won't be able to trade or win the fight.
Now if you take both Conqueror and Trinity Force away, or atleast just the Trinity Force, I assure you that she would be less oppresive and seem much more balanced in all of your point of view.
