How to get out of PVP Zone

So two things:

First, every character can learn every crafting discipline. You won't even lose progress. The catch is that you can only have two active discipline at once (as in, can craft things with them), and it costs money to switch between them, based on how highly skilled a discipline you're switching into. (If you switch in to a discipline you have no experience in, it's free!)

Second, most untradable items are, in fact, account bound, so you can freely store them in your bank and remove them. I assume the actual Legendary Weapons will bind to a character, but the materials can be passed around willy nilly.

But Crafting in Guildwars 2 is very much its own part of the game. Crafted gear is equal to gear earned from any other number of options, and is not inherently better. The only real "perk", if you want to call it that, comes from convenience.

The banner lasts for one hour, and the buff that you can get from it also lasts for 30 minutes. This buff can be refreshed by touching the banner again before it disappears.

All consumables created from influence will become available upon completion rather than activate upon completion.

Also, not only can your guild members use your guild's banners, but any players that touch it can (not including opposing players in WvW).
