I haven't played it -- I've never really cared for the BG series -- but #2, #3, and #4 just scream "I'm playing an early access game!" or "I'm playing a tech demo!" They need testing on certain elements and want players to give feedback on certain elements, so, yes, they feature those elements. I'm not sure why that would upset you. I don't mean to be rude, but I genuinely don't understand what you were expecting from an early access game, because this sort of experience is exactly what I would assume would be there.
#5 seems... eh. I mean, if you rename the item "healing potion" then it's literally how D&D has worked for 50 years. If the item being a joint of meat breaks your verisimilitude then sure, okay. But isn't that at least a little quibbling? It almost sounds to me like it's an inside joke for Castlevania wall meat.
I'm not sure what you mean by #1. I assume you mean the pathfinding when moving the party across the map? That is actually one of the most complicated things to tune, so I wouldn't be surprised if it's working poorly in an early version of the game. I wouldn't be entirely surprised if they never fix it because game development is always rushed, but tuning the pathfinding is deceptively complicated. That's why so many games screw it up.
