Yea, I agree.
We would need, at the least:
2 announcers (For the face/heel dynamic)
1 backstage interview
1 on-screen GM of sorts
We could have 4 announcers (2 for each show), and 2 separate backstage interviewers (1 for each show). We could also have 2 different on-screen GMs. But I don't think RTW is big enough to handle that much backstage staff.
A specialist referee and ring announcer aren't as necessary, in my opinion.
