no thank you.
in my opinion , making everything tradeable would be the single WORST thing that could happen to D4.
look at the state of D2 and even D2R one week after launch : it was bot and RMT paradise : everywhere there was bots : in any public baal , diablo cow.
even in your own game they would sometime jump in to spam about their website.
and even in lobby.
as stated by blizzard numerous times : the high end items should be farmed and earned by actually playing.
not being given , traded for thousand of pebbles or through RMT (pay to win)
the fact that gold and rare items are tradeable is already bad enough.
just look at any topic saying the contrary of yours and how many likes it has :
