Haste and holding aggro with procs

[ownrage]

So I was thinking...they say u proc more with slow applied to u...since that's a bit extreme would just being non-hasted cause u to proc more than with haste? If so, assuming stun+dd procs, would it be better to be I hasted vs hasted since we know aggro is based on swings and not dps outside of procs?

Just a thought...
