The retainer system is utter, complete, 100% *********
It is so bad, it's actually hard to describe in proper terms.
You walk into a dark, choking, dimly-lit cavern-room-thing where 300 ZOMBIES are just standing around.
That is, actually you can only see about 20 of them at any given time (model loading issues).
You check each bazaar by opening the main menu (takes 1 second) -> check bazaar (takes 4 seconds) -> scroll through the bazaars list (takes at least 10 seconds for 10 items) to just see the frickin' prices (they aren't shown in the overview). And if, after an hour of mindless clicking you actually find what you want, make sure to write down the price. Because one of the other 299 Zombies might have the same items cheaper.
And I don't even want to talk about the hassle it is to set up your own retainer. ARRRRGGGHHHH!!!! YES, I WANT TO SELL THIS!!!?!?! WHY DO I HAVE TO CONFIRM IT A FRICKIN' 4 TIMES!!! THE LAG! THE LAAAAG!
Yes, I had to make an extra post for this.
