My friend is lvl 60, hasn't done any inferno mind you. But he bought a magic 1 hander from the AH. It's dmg is over 500, which is way more than ANY sub lvl 60 legendary weapon, actually it's also higher than some lvl 60 legendaries.
Itemization for the legendaries (sets aswell) are also really bad. All of them pretty much, except for a handfull, have random stat affixes. Meaning you might get a legendary bow that has +str or int. Which makes no goddamn sense. Even some of the stats that are always there don't make a lick of sense. I was checking the AH earlier for legendary bows, one of the bows had int on it, first I thought it was it was one of the random stats for the bow, after checking the 20+ version of that legendary bow on the AH, it turned out all of them had int on them. Seriously, WHY would demon hunters want int on their weapons? Answer - they wouldn't.
As it is right now, legendaries are pretty much rare items that has 1-4 specific stats on them, and 1-5 random stats. Which is really bad imo. It's hard enough to just find a legendary atm, but finding one that has stats that are good? Fucking impossible.
