I think that leagues should set long term goals. Upgrading the Fortress shouldn't be immediate. It's a task for an entire league to work on. At the same time this is a realistic task worth accomplishing.
Lord Oberon,
That sounds great in theory, but the problem is that there are "safe" zones only at lvl 5 and 8. There are some very powerful leagues out there who may choose to attack fortresses in pursuit of their own goals. After all, anything that isn't 5 or 8 is almost guaranteed to have lots of def sitting there...I can see that being a big kick me sign during PvP tournaments when a league is pushing hard for first.
With the time it takes to upgrade (if you don't pay), it sounds to me like the feature is designed to force you to cash or to constantly have your hard work downgraded by stronger opponents who are hitting your stuff in pursuit of their own goals.
