Why is the new Irelia a Mage?
K I just went down the Irelia rework, and I have to say..... someone in development didn't think through these AP ratios/the utility from a melee AP champ.

I'm pretty sure she's going to be pretty strong on the following build item example:

The reasons I come up with this build?
Her Base stats will be 131 AD at level 18, and
will boost that to 197 AD.
adds 40 and
adds 25 + 2% of mana at 18 (with Lich, that's 2200 Mana *.02 = 44)
That's a total of 306 AD (+ runes)
Now, for AP: 240 pre rune AP.
If you look at Irelia's damage scaling, all but her Q is AP scaling. But it's not just that:
Q with this build:
4.8 second cooldown even if it doesn't kill anything, 0 cooldown it if does OR if it hits a mark (meaning you can Q a champion 3 times if you apply marks correctly without cooldown)
Applies on hit:
304 base damage Q,
applies
for .5 * 197 (Base AD)= 98.5 damage + .75* 240 AP = 278.5 damage.
applies
for 51 damage.
applies
for 132 damage.
Q total damage: 765 damage.
But here's the kicker: W: 7.2 Second cooldown 65% incoming damage reduction, PLUS 10% of AP in damage reduction. In other words, 24% MORE damage reduction, meaning while in W, Irelia will reduce incoming damage by 89%!
AND IT CAN'T BE INTERRUPTED
Damage on W: 787
E:
6 Second cooldown 456 damage
Ult: 54 Seconds
Initial hits 568 Damage
Does another 568 Damage if champs try to pass through the walls.
And most of the damage comes from AP.... not from AD.
In one correctly executed combo, this is 4,674 damage, for those who don't like adding it up.
And this DOESN'T INCLUDE RUNES (Sorcery Runes will put her W over 100% damage reduction, and further buff her damage on all but Q.
That's also not including her passive.... which can do up to 288 damage if the target has a shield on.
You might be able to get a better output by changing out
for a
, but the point is..... Irelia is now a Jax at high levels. Can gain 100% damage reduction, mitigate a ton of skills, disable attacks while not invulnerable, and deals 4600 damage in one combo, and resets.
And it stems from AP.....
etc if built correctly....
