This is an old program but still a very essential one. It parses Combat files and gives detailed encounter information. If you are not using a combat Parser when coming up with builds and rotations then you are just guessing. Number crunching does not work when you figure in the Human part of the equation!
Advanced Combat Tracker has available Plugins for at least three of the games we play. Rift, Age of Conan and Secret World Legends!
If you need help getting it going post here or just get a hold of me!
