Apologies if this has been addressed, but my search came up empty.
Are rares and legendaries going to bind on equip? It's been 10 years, but I think I remember that they did not in D2, so you could use something and then decide to trade it.
I'm guessing they won't, especially with the RMAH, because they will get more money if an item can be sold repeatedly. If that is the case, I bet it will be rare to find a great bargain, as people will spend countless hours lurking the AH solely to buy low and sell high. I may try to sell things occasionally, but I'll never spend a dime to get gear, via RMAH at least.
