I love new Irelia, BUT...
There's a voice line that needs changing.
"A mastered weapon needs no haft."
Irelia wields swords, which don't have hafts. This line should've been "A mastered weapon needs no hilt," or "A mastered weapon needs no grip." I mean in theory, sword staves have what could be called hafts, but there's no indication that's what Irelia was raised on. Particularly since the only Asian martial weapons I can think of off hand that possesses oth a swordlike blade and a haft are the Japanese naginata and nagamaki, neither of which are technically swords.
Perhaps we should change Irelia's epithet to "the Polearm Dancer"...
... Wait, that almost sounds really bad out of context.
