Searching
Will the new system include a tool to search within specific criteria for items, replicating what indexing sites have done, or will players still have to rely on third-party websites for this tool? Worse even, will these third party tools even still function, or will players have to wade through endless seas of Rustic Sashes to find the correct one for them as was the case before indexing sites arrived?
Buyouts
While I respect the no-buyout plan for the new system, will that new system disallow players adding buyouts to their items on third-party websites also? If not, my intuition is that most people would still rely heavily on third-party for fast, hassle(haggle)-free trading as is prevalent currently.
Limitations
Will players be limited in the number of stash tabs dedicated to trading? There are many ways of doing trade - some players will concentrate only on top-quality items and the occasional big payoff sale, while some prefer to liquidate large amounts of mid-tier stuff for small amounts at a time. Putting a limit on stash tabs to be made "public" is forcing traders into a specific mold - is this the current plan?
Asynchronism
The concept of not having to log on or be in front of the website at the same time as the other player is appealing, but somewhat counter-intuitive. My brain is oozing questions... for instance, if I accept someone's price on an item and click OK to send my currency, but they decide to not be online for a week, what happens to my currency? If I make offers on three different versions of the same unique then log off for a week, and two people accept my offers while I'm away, am I buying both?
Trade threads
I love my trade thread. I've put a lot (a LOT:
http://www.pathofexile.com/forum/view-thread/546686) of work into it, and still maintain it as would any good shopkeep. I regularly get compliments on the OCD'ess-ness of the thing, and people (surprisingly often) come back as repeat customers because of it. I'm not trying to brag here, but the question is: will I still be able to keep my trade thread as it is and put in love to have a "unique" type of shop, or will I be forced into a samey-samey predetermined layout and format for my storefront?
Communication
If trade is possible without logging on to the game, will players have to use the current
abysmal PM system on the website to barter, or will a new communication tool be put in place?
So many more... let's keep it short and readable for now.
