Suggested Ekko Buff
While not the worst champion, Ekko is a bit weak at a 49% winrate this patch. I suggest a minor buff that could be useful in the right situation. If Ekko's ultimate is available when he respawns, he should be able to activate it within 4 seconds of respawning to allow him to ult back to where he died. It fits him thematically, allowing him to rewind his mistakes, and it also allows him to do some epic backdooring or whatever he wants, while not seeming too broken.
