SW3 - skill tree and help needed

[Raga]

Thanks Simbal:

I really doubt in the repair values.
My Mothership (Mastiff) has a module 2hp/s installed.
My calculations show that Mastiff eaten to 50% hp (1500hp total) should be rapaired in about 6 minutes, but in reality it takes maximum one minute.

The problem with hard difficulty is that the 4 pirate Captains in 3rd generation ships eat all the shields of mothership (about 800) in one approach, two more approaches and you see Game Over screen.

The sad thing is that Your 3 pilots cannot even destroy one nemy ship during that time - believe me, I believe I have chosen good perks and equipped my ships properly.
