When a faction owns a fortress they receive much more ceramium medals than the opposing faction. This is a huge benefit itself. The instances within each fortress should be open to all. I know it can be done because on NA we have had events where they put MKA entrances in our Abyss base, and Sillus fortress, Silona Fortress and Pradeth fortress, entrance in the base in Katalam.
-Also, these are daily things to do. Running MKA keeps players ONLINE--and it gives them something to do. Same with running Silona and Sillus.. Also--this is a huge patch to not run Sillus (this is where most of our composites come from)-just check our broker and see there are almost no composites on there now. This has nothing to do with the past event, it is because we lost Sillus over a week ago now.
