More haste currently means:
-more LS procs with UF:WF
-more MSW procs (with the t15 2pc and many sources of haste through gear and stuff like bloodlust, elemental mastery/ancestral swiftness, raidbuffs, trinkets, troll berserker etc., MSW's priority rank rose as it would otherwhise mean more wasted charges than before (I've seen priority lists with MSW above SS and LL, so, similar to wotlk, it would mean that haste would improve on that high prio dmg source)
-more legendary gem procs
-faster Feral Spirit/Fire Elemental Totem attacks
-FS scaling with it (does it? I think it does)
-more auto attacks/ wf/ft weapon procs
