A thing to note: While for instance
Dragonstrike seems to be an excellent MH weapon, due to WF mechanics listed in OP, it's actually quite bad for Shamans, reason being that it's hard to find a decent OH weapon that wouldn't eat half of the WF procs.
Unless you can get your hands on
Rod of the Sun King from Kael'thas or
Syphon of the Nathrezim from Supremus, it's probably better to MH something else than Dragonmaw / Dragonstrike or
Black Planar Edge /
Wicked Edge of the Planes.
