You should remap your keys to gain better and faster access to your utilities.
The spaces are left blank so if you need to rebind any other key, like if you need moar than one function key (F1 etc.) you can bind them on Y,U,I, and O for instance for easier reach.
V is now your loot/talk button. Remaped from F, edit: clarified this point.
WASD is now moved to ESDF and moar room has been made for the elite skill and weapon switching is now set to Q, this should make it easier to move while useing your utility skills.
Also the bump on the D key in the picture (formerly was the F key) will make putting your hand back into place to start moving again easier and faster after you need to reach for a key, now you will always come right back to the right keys that move your character without having to look.
Your heal is now remaped to W from the number 6 key, you can now heal without having to reach for the key, also all of your utility skills can be used without reaching.
Keys 1-5 have been moved over by one space, this will keep the familiar feel of reaching for the correct number key when you have your movement keys set to ESDF.
Q is now your weapon swap, again this is why you should remap the movement keys, you can now reach the weapon swap key without lifting your had off of the keyboard, try this if you don't believe me, I have stubby hands so I like my keys close, if you have long fingers you can always remap it to 1 and move the F1 key to the U line.
A is now the elite skill and is again easier to reach.
G, H, O, and I can be set wherever you like to have your menu options at, I just leave them along that line like they are in the picture.
Tab targeting is now faster and eaiser to reach, you can set it to closest enemy and quickly drop your middle finger to press the key.
Hope this helps you feel you can reach the keys and respond better in GW2
