The 1.2 patch resulted in a fairly significant change to the the power drain mechanics of weapons. As a result, I have been running combat tests to determine how weapon damage scales in the new system, as more weapons are equipped. I've now performed a fairly extensive number of tests so that I am confident in the results, and will be posting them below. But before I do, I'll include a quick guide to how weapon power and weapon power drain works in the game. If you don't have a good grasp of how these mechanics work, then the guide may be of use to you. On the other hand, if you already are aware of how weapon power works, then you should probably just skip to the test results, which you should find of more interest.
