Quess on Upcoming stealth change

When I saw the post of how Rengar is getting a new ultimate and how they were going to change the invis mechanic, I thought about this for a while and thought of a game similar to League. It's a mobile game and is literally the same with more and different champions and faster paced. (BTW its a Chinese game so maybe not the best if you want to play it) There was a champion that had a different stealth mechanic for its ult. It was like an Evelynn passive where they could see you at a certain distance but you could only warp to that max distance. This had a little couter play in the game as if you warped, it takes a second for you to complete the animation and you can only hit the enemy if they are in the circle of where you can ult. This is like kassadin's ult but if you can make that a leap and not targeted, that would be great. There are several ways to use this as you can warp right out of the enemy's radius and even though this won't damage them, they would still be caught off guard with it. Maybe this isn't what RITO was planning on but I think this is still a great Idea and if Rengar doesn't have this kind of idea to it, maybe it could be added to Evelynn? RITO MORE ASSASSIN CHAMPS PLZ

All I want to do is to bring back to the meta..... The Chinese game of LOL: (https://i.ytimg.com/vi/1IMc9bXK07M/hqdefault.jpg) https://itunes.apple.com/cn/app/wang-zhe-rong-yao-wu-chu-bu/id989673964?mt=8
