BranchSim is a DPS simulator for feral druids in World of Warcraft. It's able to read various options in from text files to allow for customization without needing to compile the program yourself and parses XML character files from Rawr for stats, procs, buffs, talents, etc.

BranchSim is similar to FeralByNight by Nightcrowler, but focuses more on modeling a rotation that is realistically executed by a skilled human player rather than computing the absolute maximum DPS possible. It also aims to be a useful, user friendly tool for everyone, not just people with programming experience.
