It been long enough on the nerf that they did with the Fortifications. and broke the battle system for campaign.
There nothing wrong with people leveling up there skills levels on a Fortification to lv 50.
There nothing wrong with people leveling up there skills with no tags up to level 68.
There nothing wrong with people hitting the Fortification for experience points anymore, since can get 100 times faster in abyssea. and you can skill up fast enough with the foods and the items out.
If worried about to many allied notes then just cut them in half.
Now days for the last year or more damn near impossible for a server to get access to the throne room, and that pretty much outdated.
