In my experience, choosing the least popular was a pain

Part 4: The Skill Reset - At some point you'll want to skill reset. I suggest move on to 1 Element at level 40! Ditching the dagger skills (it doesn't have to be the dagger itself), will give you more altis gates gold points to put into your masteries.

Part 5: The Builds - I suggest you focus on your masteries once or if you stick to your element. It really strengthens it. If any extra, do your choice of the Misc. Tree; either Critical, or ... if forgot.

Part 6: The Dungeons - As I suggest for MOST classes, Instances should be done at a higher level than necessary. I.E. Invoke Instance should be done possibly around level 35, as it will be easier. Level 40, (3 Skills if in 1 element) is good too.

Part 7: The Class Change - Choosing your class is hard. Most go with Bards, some go to Sorcerers.

But here's what I have to say: Don't choose the least popular. Choose what you love to do. In my experience, choosing the least popular was a pain! I didn't have fun either.

Part 7.5: Bards - Bards are basically the healers of the class list. They have extremely useful buffs, ranged attacks, and they hold a guitar! Who doesn't love a guitar?
