So much for my "46 is an upgrade for both 45 AND 44" theory.
Allie's post above sums up my views entirely. "Why those 2 classes?" Because I happened not to make a haste item for them in ToT, and then looking at that, went and made a similar-tier 46% haste item with all the melee dps classes on it. BLASPHEMY!
It's kind like how some classes get 25mana thaz augs and some apparently don't. And how cleric thaz arms are ridiculously good and irreplacable whereas no shaman pieces are, or how all the dual wielding melee dps classes get access to Screamstrike except rangers, or how all the healers except clerics can wear Bracer of Forgotten Battles or how only classes with Bane spells can wear Conviction or how only classes with disease spells can use Choker of Putrefied Gore or blah blah blah.
That's just how it is! And I rather like it this way, so expect more of the same wherever I'm concerned ^_^
