My overall interpretation was he wants to make jobs easier to play so encounters will be more about learning the specific fight rather than learning to manage your buff timers around the fight.

Any change is going to have both its fans and detractors. Just looking at BLM in this very thread we have some who hate it at 60 and others who found it dull at 50 and appreciated the increase in complexity. I'm guessing that going by their data SE thinks more people fall into group 1.

I think they were going to have to overhaul rotations for 4.0 in any case. Most of my jobs now take 2 full hotbars on controller (Arcanist takes 3 if the pet is on manual control) and I wasn't looking forward to having to fit more abilities in come 4.0.
