Why didn't Ekko...
JUST PICK UP A PIPE/STICK/ANYTHING AND JAVELIN HURL IT WITH A WARNING MESSAGE ATTACHED?
It's not like there were any buildings to obstruct the trajectory(the guy was running on ROOFTOPS), and he could've easily perfected throwing form and aim with his INFINITE REWINDS. Like man, I get that your adrenaline was pumping, trying to save your friend, but after failing the third or fourth time, YOU SHOULD REALIZE THERE ARE MORE OPTIONS THAN RUNNING THE WHOLE WAY. If you can perpetuate the present, you actually have the option to stop and think.
Why can't, for once, someone with a shred of creativity get the time-warping powers? Tragic failure/claw-your-way-through stories are emotionally moving-- But there's an entire universe of unexplored possibilities outside of what's been redone over and over again. Success through demonstrated calculation is just as inspiring as will-power through inevitable defeat and despair.
