The pattern doesn't make you good at your job or not, if you are incompetent its not the patterns fault.
Only way off hand I can think of her being really beneficial to the light was when she was captured. But in the end like when I mentioned once how the plan to trap Rand in Tear seemed needlessly complicated and elaborate. I was told that's how RJ wrote it and if they just appeared by Rand and killed him it would be a very short series. So I doubt the pattern was ruining moghi's plans and schemes. She attempted some things like I am pretty sure it was her that impersonated Sam to send trollocs after Rand but her biggest failing is she was a coward.
Mog was not inept. She seemed quite intelligent and cunning based on everything I see her doing in the series. Her being a coward is what gave her her power in a way. It made her cautious and careful in a lot of respects.
And the Pattern not screwing with her? She would've killed Nynaeve but pigeons threw her aim off the second she fired. The timing meant that HAD to have been the pattern. She also led to Birgitte becoming Elayne's warder by bringing her out of the world of dreams. I considered that a pretty awesome moment for her though. Especially considering she had just been hit with an arrow at the time.
