As controversial as they are, I've used rotation addons for as long as I can remember. not so much for the dps, but for everything that happens. having everything right beside my toon helps since I have no peripheral vision. I lost my left eye more than a decade ago and its always made looking around my screen and refocusing a big pain. I use icehud for both hp, mp etc. and I used clc then ovale to ceep procs cooldowns and other info right beside my toon. I've tried setting up bartender and others but I still have to glance around to much. If an addon auther could make their rotation package work for classic that would be awesome.
