I'm Bored, so I tried reworking Irelia
Passive - Ionian Fervor
Irelia heals for a portion of the damage she deals, increasing with each enemy champion near her.
Q - Bladesurge
Irelia dashes in target direction, dealing damage and applying on-hit effects to all CHAMPIONS she hits. She also reduces Bladesurges cooldown by 2 seconds per target hit. Does not affect minions and has a high base cooldown.
W - Hiten Style
Passive: Every 4th basic attack deals true damage
Active: Irelia disables her W passive for a few seconds and gains bonus Life Steal.
E - Equilibrium Strike
Irelia damages and slows target enemy. The damage is increased the lower Irelia's HP is, and the slow is increased the higher her HP is.
R - Will of the Blades
Irelia gains 4 blades to shoot as a skillshot (similar to live) these don't heal Irelia but do pass through minions, they stop on the first enemy champion hit, and cause Irelia's next basic attack against that target to dash to the target (kinda like Illaoi E). Blades don't do a lot of damage. Irelia can fire 4 blades but cannot mark and dash to a target more than once, however, previously marked targets can still block subsuquent blades.
Thoughts?
EDIT: First update round, thanks to The Bearded Bard and Photos of Ghosts for suggestions.
, and he is ... meh. Pretty OP if viable, so RITO keeps him in over-nerfed state.
