Levelling Mesmer
This is just my opinion so you’re free to ignore me…
I leveled my Mesmer with a staff until about 40is and then grew to hate it. It’s just too slow for my personal play style. I would suggest that if you like the GS (and who wouldn’t) that you take a look at the build in my signature. It’s a power-based build that revolves around stealth. Esentially, I drop my little friends and then dance in and out of stealth until the targets are dead. It’s a ton of fun to play as you can take down multiple targets quickly and if you get into a bad situation, it’s always easy to escape.
