Hello
There might not be any ninja/TA guides but there are plenty of ninja/* and */TA guides, so it shoudnt be too hard to make a build. I dont see any reason why ninja/TA shouldnt be a good combo.
Here's a sample Build i made quick, i dont have a lot of experience with the sets though. I didnt take stamina cause TA doesnt use a lot of end. Neither did i take any of the attacks cause i rather spend my time debuffing. You can swap some powers to fit in stamina, leadership or some attacks. Here goes:
