Multiplayer background restriction

[Glytcho]

I really dont like not being able to use a background because the host doesnt have it unlocked

Specifically the class unique backgrounds, if the host hasnt completed the game then no one else can use their unique background

Same here, it's been mentioned several times, so the devs should know by now...
I hope.

The biggest irk about this is that the game doesn't explicitly tell you that the host doesn't have the background unlocked. While this is obviously apparent with starts like Boomerang and Elements, backgrounds like Bookworm don't find this out until the game starts which, like, totally sucks.
