I guess my plots are a little confusing: basically, I created the graphs assumimg haste effects didn't affect the proc chance, observed a contradiction, and threw out my assumption.

The real procs per minute (total procs divided by minutes in combat) was very close to equal in all my tests, both hasted and unhasted. The PPM shown in my plots is assuming the proc chance is based on unhasted weapon speed, i.e., reported PPM = proc chance * unhasted weapon swings per minute. Since the proc chance goes down while hasted, this reported PPM will be lower.

To be entirely clear, if you're single wielding and have an item with a 2 PPM proc on it, you'll get 2 procs per minute regardless of any haste effects you have on you (assuming no misses/dodges/etc).


I should also note that I didn't test any specials, so I have no idea how the proc chance for those is calculated.
