I'm not sure any of us would enjoy playing our job with the procs being the same for the entire rotation, even if it is more actions over the whole period of time it's not as exciting as before. Having WM for you to dump all of your buffs while you've got procs every 1 or 2 gcds, followed by MB for a proc to press every gcd, and then AP as your short breather was a very comfortable rotation, even if we wanted AP to be less clunky. I appreciate the MP management bits at least, but it would probably make us too OP and require every skill to be neutered. And considering you wouldn't be able to control when your mp gets used, it seems vestigial overall. I, and I think a lot of us, care more about the buffs we supply to the party and less about personal buffs.
