If specialization is introduced, I don't think that the problem of folks leveling alts in order to continue to max out all crafts will be as widespread as people fear. For one thing, unlike in FFXI, you pretty much need all crafts to 50 to be an effective crafter in even a single craft. In FFXI, the only reason you needed multiple crafts leveled is for certain recipes which required a "subcraft", and in general a given craft would only have two, maybe three other crafts that made much of an appearance in its recipes. Though, to be fair, the effort to level ALL crafts to 50 in this game is only a drop in the bucket compared to the ludicrous grind it took to level even ONE craft to 100 in FFXI. Or even one craft to 50.

For another, due to trade restrictions between alts, crafters will need to find other ways to exchange goods between their characters. There are several options, and all of them are pretty ugly in one way or another:

- You could pay for multiple accounts to Friend each other, one for each craft you want to specialize in. That costs a lot of real life money.
- You could become the leader of a Free Company to use the common-area storage. This prevents you from joining other Free Companies.
- You could join a linkshell that specializes in swapping goods between players' alts. This depends on the goodwill of the folks in that Linkshell - and to be honest, the main value of being a do-everything crafter is so that you DON'T have to depend on other people to craft, so this is a step back to square one anyway.

Will these things happen if specialization is added? Sure. Will it grant unfair advantages to those who do? Probably. Will it be rampant? Not likely. Most crafters will pick a specialization and stick with it, and not futz around with alts or multiple accounts, or anything of that nature. The folks jumping through all these hoops will be rare and outside the norm.
