I tried to post this on the official forums, but my login won't work for some reason (yes, I'm sure it's correct). Posting here in hopes that someone from SE reads it.
Please, for the love of baby chocobos, either add more Summoning Bells outside inn rooms or allow people to craft in their inn rooms. I get horrible lag in the market areas due to the sheer volume of people, particularly around the Summoning Bell. At first, I was just annoyed with crafters who did their synthesis at the market area Summoning Bells, but after starting a second craft, I am beginning to understand why they do it. In a sense, I suppose the market area congestion is an extension of the issues SE has had with the servers.
There's really no good reason not to allow crafting at inn rooms. Oh, I understand the whole storyline of having peace and quiet, but idk... add some soundproofing or something.
