While I might agree there are limiting options for a melee, I find it very hard to believe its why its very often suggested in most build discussion threads to choose Dire Charge regardless of melee class. I think rogue is the only one I haven't seen suggested, but very shocked to see suggested for likes of a melee ranger. There was even a thread not long ago expressing my surprise. If no other viable option is the actual reason than it would have been said in those threads and none did until this one.
