Seem to be asking a lot of question today, but here is another.
Eventually I want to complete the mission that rewards a BOFF that has Torpedo Spread III. In order to do that I need to start doing the various missions on DS 9 and Bajor that lead to that particular mission. However, I cannot find a npc that commences that chain. My toon is a VA and, neither Capt Kurland nor the Admiral have any missions, other than the 'Boldly to go' exploration missions, etc.
Could someone please advise me which npc I need to speak?
Episodes need to be completed in order. If you haven't completed all the episode arcs prior to the Dominion series, you need to complete them first. Or just skip them, you can come back to them later. Either way, you need to "resolve" those missions somehow before it opens up the Dominion ones to you. I forget what order things go for Romulans, but you'd need to at least finish your Romulan story arc, and I think maybe the Devidian arc. Also, look under the Episodes tab, it's easier to find them there than to figure out which NPC contact they fall under.
All episodes above. You can go through the list clicking the "skip" button to unlock missions up to your current level. They'll clutter up your Available list and if you have auto hail turned on they'll constantly hail you, but there's no real penalty for this.
