Are secondary attributes ever not useless?

[The Rockman]

Theres a difference between crappy and useless, +light radius is useless (no one bothered about this), +5 dex is not useless it just not ideal IE its is a bad drop unless your a low level monk or DH.
An other thing is this what would you prefer 10 items drop of which 3 are blue or better or just 3 blue or better items drop (from killing 100 mobs)?

I never said or implied that +light radius is in Diablo 3, nor that Blizzard wanted completely useless mods on items.
