Druids' Balance Tree

[playingtokrush]

I'm not so sure that it DOES proc more often.  I seem to remember Blizzard saying at some point that procs were weighted against weapon speed so that a slower weapon would have a higher chance to proc, per hit, than a faster weapon but that they would balance out to have a roughly similar level of proc'ing per time.  I'll have to go look into this at some point and see if that is the case or if I am dreaming something up.  :)

You're not dreaming that at all. Blizzard has stated that. Of course, we can't be sure that Blizzard's weighting actually gives an even proc distribution in practice.
