if pink will no longer reaveal in combat stealth

Cry.

They are implementing other ways to counter, like possibly a shimmer when they get hit by something.

I think those are the types of stealths that Riot wants to encourage (short and sweet like Vayne and Kha'zix or situational like Akali's shroud). The one's they will be targeting are one's with longer duration like Shaco and Twitch that don't have a lot of warning. That's just what I got from it.

Riot wants Vayne to be meta

what? So pinks are visible, you can only have one per person, and now they wont reveal stealthed enemies? They better atleast make them invisible again then.
