It only supports roleplaying if you bend your character to match the very limited choices the game provides now. Yes, you can own a guildhouse if you and your guildmates play the following character.
My character...
... is a miner. Sure, I pretend to do other things, but a large chunk of my time is spent mining.
... Is.... um.... a miner.
I, as a player ...
... am dedicated to spending hours doing the most boring thing in the game.
... don't have to do a bit of roleplaying.
... can try to RP at the mines, but is there a point? I would be one of the only ones there roleplaying, and I would have to RP a miner. Actually, a hard-working miner would not say much at all, as mining is hard work, and wasting your breath talking and singing would honestly be OOC and unrealistic.
I, as a tester...
... am not testing anything at all while sitting at a mine swinging a pick. We know mining works.
As for the 'auctions' themselves... only 1 bidder for two of them, and a no-bid on a third, as well as minimal if any roleplaying at the auctions? Seriously, I really feel sorry for the GMs and Devs who do not agree with or support these auctions as they are being done, but get rolled over by the ones who do. I know very well how that goes and the 'unified front' you are told to present to players. For those who keep on pushing this same type of 'easy' and honestly sub-par-roleplay auctions, shame on you for making your entire team suffer for your stubborness and fear of trying something new.
There are a lot of good ideas out there, and you have tried NONE of them in any of the auctions I did not personally run. You are not even deviating into the known types of real-life auction types. You repeat over and over how much people would complain about favoritism or unfairness if you did try another means. Well, guess what? You don't KNOW that. You are just assuming based on your own narrow minded opinions. There are many out there that would not agree with you at all. The RP auction I ran got minimal complaints, and NOTHING as vocal as you are seeing in this thread. It also did not get the now almost standard /shout THIS IS WHY AUCTIONS SUCK!
"What if a PLing guild got a guildhouse in an RP event?" Ya? So what? That just means the PLing guild stepped up to the plate and showed that they could out-do the RP guilds in roleplaying. I don't see that as a bad thing. Oh my god! The RP guilds might complain and give you a lot of flack. Well, sirs, look around you. How much worse could it get? The PLers (who I have friends I consider to be, and yes, deserve houses as well) will still be able to get houses in the high priced auctions, or can try to compete with RP against the RP guilds for the cheaper houses. 50% of each or a few mixes would do wonders for satisfying both sides.
My main point is this: Step up and get some guts. Try new things, succeed or fail. Even use some guildhouses for rewarding guilds that find and help fix the most bugs. Be Creative! Because honestly, these auctions so far have failed in removing money from the game, giving a good story, promoting roleplaying, encouraging bugtesting, and making a better community. I know, because I have seen them from both sides, player and Dev. It is time to step back and stop doing more of the same, because that is the exact reason the big three automakers are failing as well. No one wants what they are making.
And for those of you GMs, Devs, and players I know are out there who want to try new things and experiment with auctions, time to step up and start making your proposals. Don't let them be dismissed by the old (lame) standbys of "People will complain" "That would not be fair" "It is based on the current economy" and my personal favorite "I don't like that (and by default no one else should)."
