Take care of your UI, if you set it up properly it will make your time in the game a lot easier.
Remember, what works for someone else might not work for you, but I highly recommend the following addons.
- Weakauras - The most powerful addon in the game (in the right hands it can do pretty much anything you would ever want)
- Bigwigs / LittleWigs or Deadly Boss Mod - Timers for dungeons and raids
- Details - It has more uses than just damage, explore it and you will find a lot of useful information.
This is how my UI looks like
Mouseover Remove Curse Macro
#showtooltip Remove Curse
/cast [target=mouseover,help,exists] [help] [target=targettarget, help, exists] [target=player] Remove Curse
Mouseover Meteor Macro
/cast [@cursor] Meteor
Mouseover Counterspell Macro
Mouseover Counterspell and target if no mouseover.
/cast [target=mouseover, harm][harm] Counterspell
