Faster way to vendor

[Soukyuu]

....the problem is UI lag, which they're working on. I'd imagine since it's probably also a server-related problem, we could probably see some relief come server-merge time.

The way the UI works atm is like this:

Client: user pressed the enter key!
Server: good, load the selling interface
Client: done
Server: ok, load the items in the inventory
Client: done
Server: great, what now?
Client: user wants to sell an item
Server: which one?
Client: Paragon's Crown
Server: how many?
Client: one
Server: ok, waiting for confirmation
Client: user confirms
Server: good, here's one gil
*repeat*

Basically, everything has to be confirmed by the server instead of handling the UI client-side and just tell the server the user wants to sell x items. I also don't see how server merge should relieve the issue when we're going to get even MORE players per new server, thus getting more server load.
