Irelia is a really good example of a champ who suits 750 RP skins
The Order of the Lotus Irelia skin is such a prime example of how to do a 750 RP skin well. You took a champion with very light particles and gave her a skin tier that suits her, only giving her a particle on her R because obviously it features her weapon, which is a changed model. If this was a 975 RP skin it would almost certainly suck because it's really hard to give a champion like Irelia noticeable particles so that the skin feels worth it. But 750 RP fits perfectly.
Can we get more 750 skins for champs who actually naturally fit the tier? After the Syndra fiasco it feels like skins like this (another example, the Sivir, Nautilus and Warwick skins recently) should be complimented for making sense. Certain champs just better fit into certain price tiers and I'm glad Irelia got a great skin that is just right for her.
