I own a G13, but I haben't been using it for GW2 until now. The reason, I bought it was, because I played mostly shooters (GW2 is my first MMO) and the G13 is more comfortable, than a Keyboard.
Now, in GW2, I thought, using the G13 is a bad idea, because basically the F1-F4 keys and the number keys above wasd (especially 1-5) are missing.
My keybindings were: standard movement keys, F1 moved to R (my main is a necro, so I need that one more often, than F2-F4)
1-5: weapon skills
y,x,c: utility
mousewheel klick: elite
mousebutton 4 and 5: healing skill and looting
However, I've observed myself still klicking a lot. Yeah, I have to stop rotating my camera to klick on a skill, but when I use the keyboard, I have to stop moving (or at least my movement becomes less precise).
I don't think, klicking takes more time, because: moving your finger from one key to an adjacent one requires a movement of 2cm. With my sensibility settings, it also takes about 2cm to move from the rightmost side of my screen to the leftmost side, so klicking almost ever requires less movement.
So basically, I can't use my skils, without affecting either my movement, or my camera rotation, so I either klick, or use the keyboard, whatever is better in that moment.
Now, I've been a little creative and made up a keybinding for the G13, the idea behind this was to be able to use skills and move at the same time, without too much interference.
The idea was to move with the thumb stick, instead of "wasd" and use the keys for my skills.
This is, what I came up with:

Basically, I use the first row for weapon skills (1-5) and the second row for utility skills (7-9). Skill [1] has been moved down, so it's easier to reach. The rest has been build around that basic idea. Of course, I had to move Jump to one of the keys, so I jump, using my index finger. Dodging is also quite important, since double taping is no longer viable, when using the joystick.
I just thought, I'd share my bindings, maybe someone wants to try it.
Also, if anyone here is using a G13 of similar device, I'd really like to see your bindings.
Still testing it, so I don't know, if I like it, but since testing could take a while (don't have too much time to play) I thought, I'd post it anyway.
