I'm curious how many people who browse these forums use the default keybinds. Personally, I don't. As soon as I installed the game I removed the Turn Keys (A and D) and replaced them with Strafe instead since I've never used keybinds to turn anyway. Shortly after that I remapped weapon-swap to Q and, while I also use double-tap for dodge, added a keybind for Dodge on E. After a while I remapped most of the others as well to be, from left to right: 1,2,3,4,5,g,z,x,c,shft+g. I also remapped my social binds Guild=Y, Friends=Shft+Y. There's also Auto-run bound to R and About Face on ~.
To add in case someone finds value in it - I main a Pistol/Shield Engineer and alt a Scepter/Focus-GS Mesmer. I also primarily play w3 and run the occasional dungeon.
