*> Skype was originally a peer to peer application&
Sure, but Skype adopted a peer-to-peer design back in 2005 or so when expectations were a lot lower - no smartphones, no group calls, no 1080p, no cross-platform, and if it's unreliable or needs some fiddling around to get it to work properly, such is life - because the competition was paying $$$ for an international phone call that wouldn't have any video.
These days if you want to compete with Skype and Google Hangouts and Discord, I expect my regular four-way video call between people using Windows, OS X, Ubuntu and ChromeOS to establish first-time with clear audio and video to all users.
If anything, P2P high bandwidth connections are often more reliable as your traffic likely stays on your ISPs network rather than needlessly hairpinning through a central server outside their network.
Hence why VoIP like WebRTC encourages direct media rather than wasting a trip to a server, the server's peering can often be much worse than a path between two users on residential ISPs.
For 2 users, fine. But the parent was mentioning 8 users. You can't have live conversation delays/asynchronicity that p2p'ing through multiple users would bring.
