As a monk, I find that im always pushing one button or another all the time as WW. Theres almost never a GCD being unused.
As for the OP, Blizz decided a long time ago that mana-based classes should NOT have downtime due to mana in a PvE situation, unless its a healer (and even then, blizz has a certain mindframe for healer mana usage, to the point that the only time a healer goes oom is either A) incorrect spell usage, or B) 2 healing a fight that blizz designed as a 3 heal fight)
Most mana-using classes now have a secondary or even tertiary resource to keep an eye on. Eclipse, various warlock resources, ect.

If you aren't keeping up VE, OR if you are having to off-heal, you will go oom as a shadow priests. Kinda silly, boomkins/ele shamans, the closest 2 to the priest design, naturally keep their mana up in a normal dps cycle, and can off-heal decently before running oom.
