I now have played a few matches with the ABW and I have to say that I absolutely still stand by what I wrote before. It is easy to use, and not the "well I'm experienced so of course it's easy" type easy and thus overpowered since the mindset towards this module was "high risk, high reward" but only one of those really seems to be the case.
Additionally it is very easy getting the extra points for technical kill and sabotage (or what they are called in English) with the ABW as well, so it's not only easy to use in comparison to the reward when it comes to destroying ships, it is also a lot easier to get lots of points from kills than it is with other modules for corvettes, at least it seems to be the case now.
Some of the "expert" players here were offended over me talking this way about that module but I can understand why they are, they don't want it taken away because it's so strong and they don't want others to say that they only do so well because they have the ABW.
With that said, I do admit that there might be builds that can counter the module or its players fairly well and that mine in the matches I was effected by it were not the right ones (though in my defense, I didn't play much Legendary before that in a while and so it wasn't quite on my mind), but then I don't think I ever said otherwise, my main thought making this thread wasn't that it can't be countered but rather that if it isn't countered it's too much gain for too little work for the person using the module.
