W.r.t. haste: Correct, by stacking ap you will never hit a statistical valley like you can with haste, however, it's not a "which is better haste or ap" argument. If haste provides a scalable DPS increase (which the theory states, and testing seems to support) than adding a % benifit to your DPS is not something that you can do with a consistent amount of AP. So while a single upgrade may indicate that "oh this bit is better because my dps is higher" adding haste provides a % increase to your dps that will scale with the AP you gain from other gear. Haste potential (static or proc) on an item needs to be valued slightly differently because while you can very easily say, "this pair of boots is better because I have 10 more ap with them," it is not as easy to evaluate, "Well these bracers give me a static haste value, and while I lose a bit of dps now, my next gear upgrade will have a 0.66% modifier to it's addition because of the haste on my bracers." (for example)
