A few months back I started writing notes flirting wiht the possibility of a pvp league for pathfinder in the way there is essentially a pve league in pathfinder society or other such "living" games.
I've played around in various pvp leagues that involved individuals (usually gestalt 1v1 heavy houserule fests) but nothing quite like I was looking for.
It's an intriguing idea to me as a person who likes to explore the games tactical and strategic depth to see how two opposing teams of adventurers would handle a variety of scenarios.
Obviously this required a bit of finangling with the rules to make thigns work out to a satisfactory.
For example I only allowed one animal companion to be with the group or one cohort(chosen from a list of premade npcs), summoned/created creature etc. Familiars were allowed but improved familiars fell under the animal companion rule.
Or that one team could not have more than one class in the group (which were groups of 4 with three divisions of 4th, 8th, and 12th level characters) even in the case of multiclassing (i.e. if one person dips, no one can take that class) to help prevent homogenization.
Little things like that to help things run smoothly.
Then of course there were the scenarios I wrote such as "dungeon race", "war chest", and various other scenarios that were more about teamwork and accomplishing adventurous tasks in a competitive environment than straight forward combat.
I've seen bits and pieces of the conflict pvp system and while bits and pieces of it look good I'm not sure it would have worked in an organized environment where less can be more.
Ultimately I kind of like the idea and might have went through with it were it not one of those things that would take a great deal of time and effort to get off the ground. It seems like a good way to put to rest a lot of arguments by treating it as a team game rather than a lot of 1v1 theorycrafting circular debates.
But, really, I was just more interested to see what players would come up with.
