@Riot, you did it for Zilean. Now please give us some clarity to Shen's ultimate.
Add some sort of visual indicator to the screen that doesn't add too much clutter.
That effect on the shield on Amumu, on the ally's screen. Also, an OMW ping for allies to know that you're on the way and that the fight is going in their favor. Because we're all tired of having teammates that flash away from fights we just lost several waves of farm (and in this meta, maybe even a turret) we ulted to.
If you guys could do this for the Shen playerbase, it would be nice. Shen is one of my favorite champions (He's my Shenpai, of course) and while sometimes allies get it, others don't. It would be a lot better if the ultimate was more clear for the ally getting ulted to so that they could re-enter the fight and get you closer for a good taunt on the enemy.
could turn back time on a wasted ult.
