Didn't read all of the replies but it occurs to me that a lot of people are only evaluating one side of the coin. While Blade Flurry is being tuned down - let's be honest - something more balanced, combat also receives an X% AP buff to boost its single target damage (might not be 5). Add to this that combat traditionally scales better through an expansion due to its reliance on weapon damage and I think many will find combat to be quite on point for 5.2 and beyond.
The difference is that we're no longer forced into playing it on encounters like The Stone Guardians.
