Should I add addons to my World of warcraft

Hello everybody, this is 2cool4games. I am just asking if I should add addons to my World of Warcraft account. They have a addon adder for Mac called Wow Matrix, I don't really know enough about this website yet, but I will check reviews online. Or maybe, I will wait until my sister comes back. Anyway, I told you about my epic mount yesterday, and today, I am also going to talk about dual spec. Right now, I am saving up for dual spec so I can be more awesome. Dual spec is probably really useful for changing it from "holy" to "ret," back and forth, just in case you want to be a healer or something. Update: I just figured out that if you want addons, then you go to www.curse.com, the best website for World of Warcraft addons. I am going to ask my sister for advice.
