From what it looks like, the top end Legendary 2h crossbows have the same skin with a few legendaries having spectacular skins like hellrack. There are also no set 2h xbows

They all have the same graphic appearance? I mean damn, the lvl 42 Hellrack looks nicer. Also whats with the terribly bad DPS on them? The hand xbows have similar AND higher DPS, and they are 1 hand.
IMO looks like DH is been pigeon holed into duel wielding, 2h crossbows need some love before release.
