'By saying that, you are acknowledging that Supporters would get advantages from the "MRB". BBs do not want the Supporters to have substantial advantages from being a Supporter. If it ever was to exist, it's very unlikely the "MRB" would be reserved only to Supporters.'
That is exactly what the supporter feature is, a benefit or benefits to managers that sign up. A few clear examples that greatly benefit supporters are;
Bookmarks
Scrimmage Finder
Transfer Notifications
Training History
Forum Search.
Weigh them how you like but it sure looks like a lot of substantial advantages to me.
If the MRB does happen it doesn't have to be a supporter only feature. I only categorized it that way to benefit BB. This way it would also subsidize any lost revenue from advertising.
While we all understand that BB runs like a business, the bottom line is the players don't care. The players want a fun, intuitive, and less restrictive experience while gaming.
While you would see a drop in people online during the end of auctions, it wouldn't eliminate it completely. If you are able to be online, you are online. In fact you might see an increase as it would allow people who would never be on the site during those times to bid and actually increase ads by making the people who are online refresh the screen to see if they were outbid. The MRB allows the playing field to be level in that regard and helps balance the market and the TPE.
Again, there is absolutely no reason to not have the MRB. It benefits everyone, including BB.
