Why are you mad? Will you be happier after seeing 4-5 Witch Doctor knives in a row... while playing as a Demon Hunter? It's obvious that legendary are dropping only for you, and it's SMART Loot.
Followers are nice, but not as good as you think. Anyway, I'm pretty sure you can gear them with "your" gear, any by that I mean:
WD, Wiz - Enchantress
Barbarian, Crusader - Templar
Monk, DH - Scoundler
