I hope this concert exposed some flaws in their system that they will deal with before the next EN live, and before an ID live. They need a studio (even a temporary one) they can all be at near the venue for MC segments, more group songs, etc.
Also don't invite 3 JP members and 3 ID members if they are just gonna sing one song each and not even with EN members.
Still enjoyed it, but its very much a scuffed first try that will be fondly remembered when looking back rather than a polished final project.
