I cannot stress what Nyalia said enough. Do not macro your normal abilities like that. Especially if you are at all serious about doing any raiding. It's just bad practice. Macros are great for making things easier on players In a number of ways. As others have said by informing your party when you are doing anything they should know about. It can also be good for cooldowns when playing with a controller. Since you don't have as much hotbar space, you can put multiple CDs in one slot. If you don't put a wait command in between them, you just press it once to activate CD#1 and then do a spell and press the same macro again to activate #2 Since the first one is on CD, it will skip and go to the next action in the macro.
