I am so happy to finally see an FOV slider in Guild Wars 2, THANK YOU!
I noticed an issue though when I quit the game and came back later to play the FOV had been reset back to the default setting, however the slider was still all the way over to the right. I dragged the slider 1 notch to the left and back over to the right and the FOV instantly increased again back to where it should be.
A small issue, but annoying that I have to re-adjust it every time I start the game. Again thank you so much for these changes!
