Guild Wars 2

I heard crafting from 1-400 will net you around 10 levels, but does it still stand?

I started crafting at character level (not craft level) 50, artificer from 1-100 but didnt even to gain 1 level.

Anet nerfed exp from crafting?

Depends on what level you were when you started crafting. If you were already a higher level, your not going to see much improvement in the low areas of crafting.

According to the wiki, the experience gains from crafting depend on your level (like everything else in the game). Therefore, each toon that raises their rank from r0 to r400 will gain 10 levels, no matter what level you start with. Buffs (from Power of the Mists or the Crafting Booster) will affect how many resources you use; they won’t affect the experience gained.

It’s 10 levels per 1-400. You get more levels 300-400 than you do 1-100. Keep going, you’ll get your levels.
