So excited by these new bracelet/t-shirt/talismans we decided to take a fortress for our own. Patch notes said there we 2 different ones: Green flagged Fortress (small) and a red flagged fortress (large and border). We decided to take our chance at the Western Fortress above ABG and we took it. The NPC guarding it were all dark blue to us so the knight thingies they were suppose to drop were next to nonexistent.
Anyways they also said you could earn these things in the dungeon instance of the fortress. So all not knowing what to expect we entered a full 78+ party into one. To our amazement a dark blue raid boss equivalent mob spawned that took out our buffs every time we attacked it. We had to soe out and still disappointed that we couldnt get any more of those knight thingies
So my question is, are the fortresses based on lvls such as high lvl fortress and low lvl because all the fortress sieges we had were all low lvl npcs? If so, how can you know which ones are high and low? It seems to me the only way to gain those special currency is to kill the npc guards or the mobs in the dungeon which are dark blue.
