Look like not everyone get what SE presenting here, I hope you all know what is the RPG in MMORPG stand for.
RPG means different things to different people and I'm afraid you don't get to dictate what it should mean.
For some people, it's like a play and each player is acting out their character's role in that play and immersing themselves in the fantasy world where stories are told and great deeds are done. And most of those people do it very, very poorly. Horribly. Embarrassingly bad. As in, "Don't do that **** in public channels because you look like a right sodding ******, you *********** emo attention *****" bad. I'm okay with it...if you want to relate to your comrades how your mother died during the war and your father died in childbirth and you were so poor as an orphan on the streets that your siblings ate each other, be my guest. I won't even poke fun at you if you do it in a public channel...I know plenty of other people will do it for me.
For others, an RPG is just another genre of game. They aren't interested in being actors or making up stories or anything of that nature and from a realistic point of view, those people comprise the majority. And an MMO developer needs to cater to them just as much as they cater to role-players. That's just how it works.
I mean why are they so persist and insist on market wards? Well if you put some thoughts about how the ancient/ or medieval time, there is no auction house that operate just like our stock market today. No you can't submit your bids and get that share off the NASDAQ within 1 sec.
It seems that in ancient time, when people trying to sells their goods, they have "wards" or a street where most trading would occur. SE is trying to imitate that right now.
In ancient times, those street vendors wouldn't be standing around with 78 marmot pelts, a hatchet, a Rogaedyn sized shirt and two pairs of bronze leg armor in their pocket. They'd have a cart with their wares laid out for all passers-by to easily see and even if they were broke, they'd probably find a wall to lean against and spread everything out on the ground so that you know just walking by what is available. Don't try to play the realism card here. SE can't duplicate real world conditions for something like that so the next best thing is to produce a system that doesn't suck. They're getting there with the wards but as they were at launch, it was a failed concept.
Leves are similar. In ancient time, these people doesn't have a mark on their head floating and shouting "I want someone to do this, will pay for your success". No, they don't. Agency and billboard is one of those thing people use to communicate and want things done.
In ancient times, if you slaughtered the flock of dodos that were eating all of the farmer's crops, they wouldn't be back 36 hours later needing to be slaughtered again. In ancient times, if animals were tainted by the pages of an evil magical book and you killed them, the odds of the exact same kinds of animals showing up in the exact same place with the exact same problem 36 hours later would be slim to none. In ancient times, if I had a hammer and a forge and some metal ingots, I wouldn't need to harness the magical powers of the elements to hammer those ingots into various different shapes and I sure as **** wouldn't end up with a super-destructive miniature ******* tornado destroying my work halfway through.
Again, don't try to bring realism to a fantasy game. The whole idea of fantasy is that you get to bend and/or break all the rules. A developer's role is to try and make a game that mixes just the right balance of fun and challenge to be entertaining and after 8 years as an MMO developer, SE is still learning how to do that.
