It turns out there is a rounding issue with haste such that just looking at the ratio of a weapon doesn't really tell you which will do more DPS, even ignoring procs and such.
So until it is fixed, here's a good guide for which weapon will do more damage at different levels of haste. As one example, you can see that the Darkglint Blade gets no benefit at all from a 5% or 8% overhaste clicky, because it ends up rounding to the same number at 100% and 105% and 108%. You can also see that some weapons, which might be very close at 100% can diverge at 105% (compare Runic Bloodstained Maul and Dragonkiller). You can even get weird effects, like the Runic Bloodstained Maul will surpass the Warsorrow at some levels of overhaste, and th Arcekor and Sekv will perform very differently depending on the level of overhaste.
