Considering they clearly didn't even think about what the burst nerfs would do to Scoundrels/Operatives in PvE, and that they didn't touch Sorcerers/Sages at all, I would wager that their live balance team probably isn't the most experienced or competent. This is my initial impression from what few balance changes we've seen. They seem to be mostly kneejerk reactions to whining on the forums, with little real thought put into them.
We'll see, I guess. But so far, they aren't doing a very good job.
