My LS does all bcs (including DM) on D-VD with no difficulties. None of them are hard if you just zerg them with a couple good dds, a buffer, and a smn. (Obviously this strat doesn't apply to them all, but it does to most). The whole having 5 difficulties still seems silly to me. With a thf it's pretty rare that we don't get 2 drops on D. There's almost no incentive to jump up to VD (which is quite a bit harder), and with the crappy drops on Normal or lower, I can see how a lot of people find it not worth their time.
