I got my reputation maxed to Legend status last week. I ran all the Heroics everyday and have gotten quite good at all of them. However.....I am noticing since I got my rep to Legend the missions are more difficult. Did these get buffed or something? I am not doing anything different and have not changed any of the ship upgrades. Is it bugged perhaps? It seems like I am not doing the same amount of damage as I was before. I don't get it. I have all of these missions down pat and its pissing me off I can't finish them when I had no problems before. Anyone experience this?
Try checking the "Space Missions Broken in 1.7.3" thread. All your questions would be answered.
There's even a dev post floating around about the issue somewhere.
