I tried out ERZ and it's excellent! I was not surprised though, I have seen the developers around the rotations scene for many years and knew that their work would be excellent.
I honestly expect this to polish out really nice with their constant development and updates to the core and classes. They support healing, DPS, tanking, PVE, PVP, and custom scripting. The setup was super easy, they have the auto bind feature which is awesome, spend less time fiddling around with keys, and just get to play the game. I'm definitely a fan and highly recommend checking them out and trying out their trial.
