Well, some people are pissed off with the fact that we don't will get an "uncorrupted" version of Xayah and Rakan Star Guardian's and they're gorgeous, shiny, etc. But, rioters already told many reasons to not exist some kind of "CTRL+5 toggle" or even a "Pure chroma".
**Very well then, so... Why not just increase the time of being "pure" of some abilities? Something like 4~6 seconds after:
Xayah's ultimate (Even if the player press R again) and Rakan's Q (Even if the heal don't complete the circle) **
Rakan has a serious problem with his "struggle" (Lightness VS Darkness) because he is almost all the time on his "dark form", we almost can't see his uncorrupted version.
I think that will be easy to riot solve, and some players could be a little more satisfied with the skin! That's it! It's VERY simple.
