there was noone on enemy team would be less than 3 levels below ekko
you could put there any champion fed to the similar level and the effect would be the same i actualy made a similar penta with vi
next thing is that heca and morgana came to teamfight without any hp so all that ekko realy did was destroy a squishy gragas and a squishy yasuo ... rest was simple cleanup
hiis ult in fact didnt deal as much damage as it seems, all of enemeis had 2 stacks of ekkos passive so he detonated both skills at once, add that to 3 levels of advantage, and loads of gold .... you get aoe veigars ult
owerall its a skill play that can either reward or punish yasuo, those guys just failed their part hard

This is why I never will respect or take low el0 players serious. You always blame the champion, instead of the players. That Ekko outplayed them, simple as that. Those 5 people were clueless and deserved what they got. Gitgud, skillz and mech0nix are all that matter.
To be fair, I can show you a 1 vs 5 of just about any champion, I can show you a 1 vs 5 post nerf Mordekaiser penta, this doesn't really prove much besides fed champions do a lot of damage.
nothing OP about that. ekko seems to be fed as he is level 18 t0 everyones 15. whoever laned against him, blame them not riot nor the champion. plus they walked right into an unwarded bush. face check penta kill. lololol
