As someone who does pvp a lot, I would love to see something like this implemented. Many including myself love the chaotic mess that is 4v4 spars, but having a FFA mode would really allow for some really funny moments. 8v8s would be harder to implement I imagine due to the nature of the game's party system capping at 4 players, however, I had an idea that might make it easier to implement. Instead of increasing party size max or whatnot, why not add an option in the pvp challenge menu that allows for more than 4 players to be on a side when adding more post-start. Players over the 4th slot on a team would be allied with that side, but not be directly "in" that party mechanically to get around the party size cap. Having a longer deploy timer with this option enabled to allow people to join in before turn one might be a good idea.

All of this of course are just random ideas from someone who doesn't know how the battle system code is set up, but I hope that might help if it does end up becoming a planned feature.
