Many raiding hunters are currently running what's called the "Meme" talent build to try and work around the shortcomings of the current MM spec design (mobility, clunky nature of vulnerable mechanic). This build heavily relies on Piercing shot.
In addition, the 4pc bonus also reduces the effectiveness of the 2pc bonus during Trueshot! Set bonuses should have positive (or at least neutral) synergy shouldn't they?
Itemization on set pieces is also quite bad overall, which further exacerbates the problem.
Notes:
- MM issues are well documented/discussed/debated by smarter hunters than me here... please read this!:

- If you're unaware of the Meme build, you can read about it here:

Sufficed to say, the Meme build vastly improves the playability of MM with relatively little sacrifice to overall DPS.
