The Erikson and the Transport Missions are not for the Battlecruisers and the Klingon Carriers.
With Erikson, its super easy with Raptors with BoPs. But with Battlecruisers and Carriers, you cannot complete the mission objectives because you can't loot the freighters while being fired on by the 4 Escorts. And if you attack the Escorts, there isn't enough time to disable the freighters.
With the Transport Raid, you blow up a freighter, it's a mission failure. Even if you already looted it. Then on top of that, fighting off the Federation Cruisers and stopping the Transports before they get to the warp point.
Even further, if you managed to pass the primary objective for the 1 emblem, and fail the secondary (for the 3 Emblems), you have to drop the mission and restart it. But due to the changes of the Mission Contact list, you are unable to restart it.
Overall, for me Season 3 is not off to a good start. I personally am disappointed the time I did the Pi Canis missions, which resulted for a total of 1 emblem, I could've done the 3 Missions in Eta and 4 Deferi Missions.
So I viewed the time as wasted. And I hope Cryptic revises these missions in the next patch.
