Ok...let me level with you here SE...

. Some will be relicholders who don't need to farm the 1-3 mill anymore.

It will still be 2 hours that they could have spent making gil/gear etc. I dare say that these people know quite well the value of their time.

Some will be people who don't want a Relic/Mythic and so have no need to step into Dynamis to farm gil.

Then they probably won't do it for nothing.

Some will be people who want the Arch Boss drops in Xarca or other zones. For those people, the opportunity cost you cite is replaced by other drops or DKP.

These are not highly sought after. I wouldn't count on it.

As for the people who do farm 1-3 mill every day who skip, in the context of a large LS, at best they likely won't find any help later on when their Relic is 99. in any event, a large LS won't spam Dyna, it would likely be an event 2-4 times a month.

Regardless of how often you do it, or who you do it with, if you do an event that typically pays a bunch of cash and you don't pay anyone, they won't do it.

Just because a guy works as a plumber doesn't mean he will mow your lawn for free.

The opportunity cost theory applies to 100% of the people who have entered dynamis. Any time you enter dynamis, you have the option to either spend that time making money, or not making money.
