Also the fact that you as a player have to set up your UI to make tracking the orbs more manageable. Like "weak auras". Since otherwise you could quickly end up staring at the UI to check for what you had to press.
But now that's not an issue since at least for me with a controller i can just set up 6 cross hotbars that cleanly loops through the entire rotation turning the abc-123 into just 123-123...
