The R14 weapons are really fine, it's basically a free raid weapon which most people get eventually anyway, BRE mogs R14 with 1 proc, Sulfuras deals more damage, Ashkandi is pretty much the same thing, R14 dagger is like 6 extra damage vs the dagger from Rag.
But the R13 set and caster weapons are aids powercreep in MC or BWL patch, from pre-bis it basically doubles your HP and gives you raid BIS levels of damage. The mage set misses like 30 spell damage from Tier 3. It's why things like Shadow priest and soul link warlock are so aids in vanilla, they are already tanky, now you double their HP with gear from Naxx patch while everyone has shit damage?
