its not really a problem with loot 2.0
you can always reroll the one stat that is bugging you, so while you won't get a trifecta everytime, you get 2/3 pretty much always.
quite a few items have one or 2 fixed stats on them
take Magefist for example which will always roll decent, no matter what
or about every bracer/belt
even without legendaries, you will outgear any dropped rare once you start crafting and reforge the unwanted property
