Guild Wars 2

hello everyone !
i started GW2 when it first came out, but i stopped playing for a quiet long time ! i just came back one week ago i’m getting familiar with the game, but i still dont know how the crafting system work, is it like wow ? you choose 1 or 2 profession to level or u can do all profession u want farm all materials u need and craft everything ?

You can have any 2 active at any time on each character. There is a fee to swap between them, but you can have them all on one character is you wish.

You can only have up to 2 active at a time, but you can swap them for a small fee.

For example, my elementalist is an artificer and tailor. If I wanted to be a chef as well, I can go talk to the chef master guy and swap either artificer or tailor for chef. At any point I can go back and do the same and re-swap chef for the one I dropped or even another new one, like jeweler.

If I dropped artificer for chef and then swapped them back, my artificer level would be the same. So you can level as many crafting professions as you want, but can only have up to 2 active at a time, making 3+ crafting professions a bit of a pain to level parallel.
