Why is Irelia STILL a balance trainwreck?
You simply cannot make balance changes these days to Irelia because she's kinda broken and has nothing going for her that separates her from other Champions (besides her passive, but Riot hates that because it's invisible power/no gameplay). She's flexible in capabilities, yes, but buff even one number ever so slightly and suddenly she's #1 OP. Nerf her ever so slightly and she's suddenly "Olaf-tier". Basically, it's the "Lee Sin problem", in that her current design means number changes simply are inappropriate for her.
And don't get me started on her ultimate. Honestly, it feels like the LEAST useful ult in the game. If it's gonna heal you for nothing in a team fight, why does that heal exist? Not to mention it's function really SUCKS for her theme; even Riot thinks it's inappropriate for her (can't remember who said it).
The question is, will she EVER get to be a priority for reworking? Or will she be forever at the bottom of the pile with other Champions butting ahead of her in line?
