If you want some decent stats on what professions are played Wingman is always a good one, the fractals page doesn't look very good for the warrior in general. But overall in high end PvE content, it looks like BsW is barely played. It's also a lot of data points, definitely some overperforming and underperforming classes in there.

Edit: They also break it up based on timeframe which is very nice compared to Efficiency (I haven't really found a place to see playtime based on date there).
