[SUGGESTION] Ekko's ult needs to get even more "psychological"

I really like the champion's idea, design and kit. But as riot mentionned in his reveal, Ekko relies more on his cunning than his strength to outplay his ennemies. To make him feel even more smart and psychological to play with/against, please remove the time-clone of where he was 4 seconds ago. This gives Ekko a good element of surprise if the player is very clever because cunning and trickery are a must to play this champion. On the other hand, if you feel this that this change may lead to an unbalanced champion, give his ult a cast time ( let's say 0.75 sec). During this period, Ekko goes back in time from the moment he used his ult all the way back to when he was 4secs ago with an animation just like in his teaser video after he switches the button in his gauntlet. I am looking forward for your thought about this idea especially you, dear rioters ! c:
