And by "make good choices" I hope that includes "no mankini". (what is a mankini? Google it. I double dog DARE you!)
Yes, the program I used was ACT, and it can be a bear to install and get working. There is a very good troubleshooting guide for the installation, though. If you follow the developer's installation directions and trouble shooting guide step by step, it will work. That said, I believe Pyre uses Combat Statistics for his DPS tracker, which is a much easier install, albeit with less information and customization. I personally prefer ACT, despite the installation headache. I'm a data junky and I like to look at other people's numbers so I can use that as a guide for my own builds/rotations.
