I’m lv 70 and really the only time I used anything other than D/D was unlocking the weapon skills. I just don’t like the flow of combat with the other weapons.
I do remember being a little squishy early on, but it was my lack of understanding on the class. Main items are
1 open in the right element. Air or Fire depending on what you are doing
2 I found rebinding the keys for strafe on the A and D keys to be very helpful, it makes for much easier circling
3 Circling is not only for PvP. Many mobs have a slight delay between when the animation starts and when the attack lands, and many of these do lock the angle in, so you can sidestep the attack without using dodge or breaking off you attack. This is the case on a many of the harder hitting attacks in early zones.
4 when you start getting traits, experiment with different builds. Its pretty cheap to reset the points.
5 try out different utility skills. And find which setup suits your playstyle. If you read around here almost every skill makes it into someone or another’s build.
