How many toons are we required to play? Because personally I planned on playing 3 but if it is required that we play more
I was originally thinking 5v5 but after giving that some thought, a team size of 5 alone makes participation impractical for a lot of people. I am definitely open to suggestions!

I think that stream/video is out of place though personally as that is judgmental on their video editing skills and not their PVP prowess.
I want to promote participation in multiboxing the PVP arenas, where clearly we are invited to do so, and videos and streams can be pretty good at doing that. I think this is a good alternative way for people to participate without necessarily thinking they can be the best PVPer, because most of us wouldn't bother trying. I want it to be more interesting... and I am open to ideas like this that promote participation without necessarily being "the best" or one of the few top people. The top PVP teams will get different rewards than people who participate in other ways.
