Wrong, Fully Legendary DH here, 7196 dex and only 33.2% dodge.Quote from Radglad
Every fully leg'd out DH has at least 55% dodge in addition to being ranged and having supreme mobility of the gods. If you're not asleep, any hits you do take usually miss
As for the topic dodge is absolutely garbage because more than half the damage in the game cannot be dodged. You can't dodge molten, plagued, poison enchanted, desecration, poison clouds (ie ghom), soul siphon (ghosts). I don't think you can dodge lightning storm either. I don't think you can dodge any sort of charge abilities, knockbacks, stuns, etc, So many things that you cannot dodge, it really is a useless stat and the main reason why demon hunters can have tons of toughness and still be incredibly squishy.
