basically the only reason i'm using an action button switch is because i have a lot of stuff on my action bar,
apart from that, when i press the button on my action bar to use meta, imho its easier to press 1 directly afterwards to charge in and then cast immo aura, cleave, sb till mc procs and then inc, telly back after meta wears off and start from 1 till . for my default rotation again.
I don't want to look on my keyboard just to see if i'm pressing the correct buttons, or having to need 2 hands just to press everything, i need to have one hand free enough to move when needed. And the easiest way to do that, is having 2 different action bars setup for normal casting mode and meta mode
the whole point of getting RDX is to skip all the addons like bartender, pitbull, kgpanels, etc, and just have 1 addon loaded that manages everyting
But for now, it indeed seems i'm stuck at using bartender untill sigg shows his face and tells us the secret answer
