More worried about the Ogre drops than anything, since they fit here best. However, you're right, it might be valuable to tier the turrets as well (at least the ones available to us in the early-to-mid-hardmode area). Any recommendations?
Unfortunately, not yet... I've yet to do any DD2 stuff in hardmode, keep getting bored/distracted in mid-playthrough to actually test them.
