Why? Aren't Auction Houses all-around better?
In this day and age who would want to waste electricity, money and RAM letting the game run while not using the computer for nothing?
I know I can't do this. AH are better because people like me won't be unable to make proper profit in-game due not being able to set shops for long.
Also, like someone already mentioned: Private shops = Bad frames per seconds. (Screenlag)
According to the game guide on the main site there's an auction house as well, so I'm guessing they're just giving you both options by adding private shops. Personally I'd stick with the auction house, but the amount of private shops will depend on the limitations there might be to the auction house, I guess. So we'll see about the lag when the game comes around.
As for the delay, I'm not really upset since I didn't find the game untill recently. Imo it's nice to see that the developers of the game is listening to the community. That's a rare sight for me and a main reason I quitted another game not too long ago. The new additions sounds really cool and is totally worth the extra wait imo. This game looks promising, so keep up the good work!
