I tried to combo this several times throughout the video but the only obvious time it should have worked is at 18:20 where Nunu finds me in the jungle. We are trading in a bush and I throw down my W and wait for my ULT clone to catch up and the Parallel Convergence clearly goes off after the ULT does not at the same time.
I have had other people tell me this isn't working also.
Cubíx1 votesAlright I was super confused on ekkos "time-break" change as well. Essentially it doesn't mean youll activate the stun early, it simply means if the dome is ready to be activated and you are on one side and the ult is on the other it will cause the stun to go off.
Ekko--------------------Dome-------------------ult
Up above means you'll pass through the dome on the way back to your ult and if the dome is activatable (so after the 3 sec wait time) it will apply the stun and you'll get the shield.
Abe1oth1 votesserieusly? that is so much less fun:(
Cubíx1 votesyeah when I came to that conclusion I thought the same thing, it actually has some really good outplay potential still, its just not upfront strength like I was hoping for.
Abe1oth2 votesyea but ekko is stil <3 Ekko main forever 
Aftermath45191 votesAh I see..... Although that is not how it looks to be explained and WAY less fun of a mechanic
