Looks like again I'm late to the party like it was with non-60 bgs, I'm actually prefer more read-only but here are my thoughts:
Kronos will attract more of those 'srsbusiness' guys since it's a very promising server, who will practice '20 lvl mule with X amount of gold' method to farm stars, buy\snipe cheap chars and resell them for real money. And what's the cost of 1 star? You can buy stars to resell char for real money, this whole system will just help people to find chars and resell them, it STIMULATES black market. Even if the auction won't be that active, it still can happen. Moreover, look how much can people spend on server with awful administration:
http://feenixservers.neocities.org/claudian-notes-backup.html 150-3000 euros, now imagine how much or how often they're ready to spend here.
Every player left == gold of this player won't be taken into any transactions anymore == cutting the whole amount of gold. It's like you're buried your account and characters. Allowing character auction will grant the possibility for gold that should've been 'lost' be. You'll let the gold travel more than it should. Same goes for GDKP and multiboxing. Reason for inflation. Speaking about inflation: think about future. Every server has it's own lifetime, for example, take feenix: Warsong and ED. Warsong(I know about rates, they just kill the server faster) is heavily inflated, everything is farmed besides KT, hard life for newcomers etc etc, dead one. ED - following the way as another project(athiarne said it himself) and will die too ofc. And I want to ask you, how long you want Kronos to be alive? When AQ40-Naxx will be farmed and people start using auction actively to probably try some new tactics, newcomers will get their naxx geared chars and what? Server will die alot more faster. In normal situation old players will just leave, and new players would have to farm everything by their own(or with geared help, ofc). On Kronos it would be possible for them to buy geared char and pwn dem p00r nubs. It IS p2w. I know, that when all content will be cleared, you'll say to me that server's nothing more to give and will start dying. But what if there's a long delay on t1-t2 content with the reason to give most-possible fixed content? Will you cancel character auction? The situation that I posted above will happen, obviously, since some people aren't patient enough. Also, is there any threshold of population upon which you going to close character auction or you plan it to be opened forever? Sorry if it's a little off-topic, but also allowing to respec for 10g will push inflation ahead, since people save 40g EVERY TIME, which is a lot -> server will die faster. IMO you should only leave cosmetics in shop.
P.S Excuse me for grammar mistakes.:laugh:
