I think the caster and melee should be equal drop rates.
But at the same time I think the melee drop rates should stay a bit lower.
I'm split between agreeing with this and not.
It would be quicker getting full Deathwing melee, but then that makes it too easy I feel.
But, I'm going to agree with this, It's somewhat annoying to never have any deathwing melee yet always having caster melee. Most people can't say "Oh hey, I have some Deathwing melee in my bags, let's sell it!". It's rarely melee that gets sold it's always caster, because of this many people have full Deathwing casters yet only a few pieces of Deathwing melee to go around for all of their melee characters.
