Party finder treasure map loot rules

[Naryoril]

I know this isn't strictly a dungeon topic, but there is no forum it really belongs to. So since some kind of dungeon is involved, i'm posting this here.

I plan to do Bara'ax skin map treasure hunting, but since the last time I did treasure maps was in Heavensward, I tried to google what people usually do with the loot.

It seems there are 3 schools of thought, and what is dominant depends on the server:

1) All FFA
Reasoning: it keeps people engaged when they can always win something. Makes people bailing after their map(s) less likely

2) Overworld map owner need, portal FFA
Reasoning: the important and valuable stuff is in the portals, that's what people come for

3) All owner need
Reasoning: it sucks if you get nothing out of your own map. also you don't need to keep track of who brought how many maps, because all FFA is only fair if everyone brings the same number of maps


What i'm thinking of doing is to combine these methods to get some of the good points of all options:
First chest, be it overworld or the one in the portal, is owner need, if you get further chests within a portal, it's free for all
Reasoning: You get something out of your own map (so you get something for your investment), it doesn't matter much if not everyone brings the same number of maps (even if someone brings 0 maps), but you stay engaged since you can get loot on every map and hope for multiple turns within a portal, even if it isn't your map.
That last point is something someone raised on reddit for the all owner need option: he feels bad when he is in a portal and thinks "i hope we get booted out, so this goes over quicker"



What are your thoughts? Am I overlooking something that is the reason nobody seems to do this? Would you join a group with these rules?
