I'm sorry but you need to adapt to the new combat missions. NPC ships do not have tactical maneuvers and officer bonuses, so you have the advantage.
Use specialized designs. I see new boarding ships with optional power armor marines are working quite nicely.
There will be new content updates very soon.
I have no problem with COMs being made harder. It was needed. What wasn't needed was reducing the pay of COM missions. I can see why people are wanting to quit over this. Not to mention there is a lot of other things that are needed in the game much more then this entire thing.
