From what I follow, I agree.
The server is there just as long, regardless of if matches are run daily or weekly. Having any cost or impact be 7x what it is on a daily does make sense. This leaves things down to player preference. If you want 14 credits, for example, will you cut a promo each cycle on your server of choice.
I am excited to see how the weekly server plays out. Personally, it suits my schedule better which is why I added a fed as soon as I saw it go active.
I do like the logic of making sure that promoters are held responsible to not overly reward their roster (which does typically include their own wrestlers).
From what I can see, I am also glad that my work on the daily server that awarded me credits does carry over that balance to the weekly server (I earned 1/7 as much as I would have on the weekly server if it existed at the time), but that definitely helps with the transition to the weekly server. I think keeping that as an ongoing option will help.
And yes, making a cost to run a fed (which could be paid with enough in-game credits) does seem good for the game. It would limit the quantity of feds and make sure that any promoters have an investment in the success of their fed.
