Racial Inventory - I dunno what you're talking about, sorry... never heard of that.
Not racial - radial. It was an alternative inventory menu in the beta for doing stuff like sending items to other characers etc. It used icons instead of the small drop down list we have now.
Loot drop - Can't say much about this, but, I'll take a long shot. I've been exploring the outside of the 1st city with my friend and, the loot seems enjoyable for now. They don't drop that many items, and some are useless, but it feels like each drop has a feel of accomplishment.
Vendor's lack of gold - Yeah, kinda true to some, but, dunno if it'll impact that much at endgame. Lack of stuff to buy? Well, I still want a bunch of stuff from them
It is not so bad in the early game, yea, but later you will start to notice the imbalance.
