Having tons of fun with co-op, but there are some stuff the I personally do not agree with (but it's my opinion, not that what you're saying is wrong).
Skill Bar Limit - Can't tank much about this yet, but, I'm used to games that don't have many skill slots, still, I can agree with you on this one.
Racial Inventory - I dunno what you're talking about, sorry... never heard of that.
Inventory Micromanagement - I like this, I really do =x maybe I'm the only person on earth that like this, but, I get bored seeing all of the recent RPG's to have a list of recipes, and you only need to gather the stuff and click on a button. I like a game that makes you memorize stuff, or even, take notes. What I would agree on is to have a tab that show only items that can be used for crafting. Still, I do enjoy the crafting system here.
Slow Running and Combat - Slow running... yeah, after a while you start to notice. Slow combat speed? That's relative. I don't mind. I've been playing co-op and it has been faster than I expected honestly. No complains on the combat speed for 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 =x
Rock Paper and scissors game is ridiculous, specially at the early levels since everyone has the same level of persuasion... this was a bad choice true!
