The one, and only reason I will not be unlocking the Final Hour icon and borders
Equipping the icon doesn't change your profile background to the PROJECT: Vayne splash art.
That's it.
Riot, please. Go through and have every summoner icon that features a particular character, cause the summoner profile to change to relevant artwork when equipped. There's so many cool icons I want to buy, but never will because the icon alone isn't worth anything to me.
I'd snag both PROJECT: Ashe and Recon PROJECT: Ashe instantly, if this change was pushed live. Just one example of many.
You only have to put in the grunt work setting this up once, and it's not even like it's a whole lot of work. You just have to make the icons behave like the Ultimate Skin icons already do. Short term loss for long term gain. It's a win/win in the big picture.
