Remember to always have your addons updated, esp after new patches
And try them all out, some you will like, some you will hate, some you will Use
I have listed more to do the same job, so you can decide for your self's what you like best.
Don't use to many addons if your computer is old and slow , that will slow your Fps and lag WoW.
