Alright, I have plans to have a Minecraft server with a mix of game modes, including Mini-games. I want all this to be on a normal Bugeecord/Spigot setup, but I also want to find a way to have a way to connect to an FTB server from lobby. Is there a way to have an FTB server connected to the hub in a way that allows both normal clients and FTB clients to connect to the hub and play on whichever server(s) they have the client for?
Well you could have a forge/FTB hub with forced host and have FTB/forge sub servers as well as spigot hub/sub servers
You will need one BungeeCord, one 1.7.10 protocolhack server, your ftb server and if you are running 1.9 minigames, a 1.9 server. Set the 1.7.10 as the lobby server and you are fine. You might need an edited version of the protocolhack. Just use google to find a version.
