What's Up With Traps?

Traps now scale with hunter stats such as hit, expertise, spell penetration and attack power as intended.


What does this mean?  Better AP damage?  Worse?  Gearing for expertise?  I have to imagine we don't change anything we do and things work better.  That's the pattern Blizz hunter changes have impressed upon me in the past year.  I do hope they continue the good job.
