Guild Wars 2

I just got GW2 and have decided to play a Mesmer (mostly PvP if that has any affect on the answer to my question), but I am trying to decide which crafting skills would work “best” for me. This is my main of course so I want something I can use, but that can also bring in cash. I was thinking about Jeweler and Tailor, but wasn’t positive. Anyone have recommendation?

Tailor will save you more money come endgame when you are trying to get full exotic armor. Jeweler is actually a viable way to make money if you get the ores yourself, and you can get trinket upgrades easily. So I’d say that those two are good choice. Mesmers have a large variety of weapons they can use so choosing Huntsman/Weaponsmith/Artificer would not be as useful, not to mention they’d overlap with the fine crafting materials that are required for Tailor. Jeweler only takes gems and ore.

I have Jeweler and Tailor on my Mesmer and I found it very useful.
I pretty much crafted my armor and trinkets all the way to 80 and Jewelry is also a decent money source at 400.
As Celestial said you should get the mats yourself since gems can be expensive.
Crafting armor to your own specs is also a huge bonus
