Quote from PhanxHowever, I can't think of any situation where you need to change the profile in a hurry, so taking a few seconds to open the configuration window and change it the intended way shouldn't be an issue.
That's like saying using CTRL-C to copy text isn't important because you wouldn't be in such a hurry as to not be able to right click and select copy.
A lot of people use different frames for healing then they do for DPSing, and when you are switching between healing and DPSing every 15 minutes in a raid it's nice to save some time. I'd also prefer not to go to the extra step of running another addon for a single purpose, when I can easily use a script to do it with what I already have.
Thank's Shefki, I'll have to go play with my macro's now =)
