Tearing around the internet earlier tonight, compiling info for an upcoming post, I came across a little gem in the form of a fantastically-designed DPS calculator. It's called MaxDPS, and after tinkering with it for a little while and watching the numbers dance around the UA vs. Ruin argument, I'm pretty impressed by it's presentation. It's fairly easy to use and quite customizable, and definitely worth a look. Give it a shot. Hopefully it'll do your DPS good.
