Guild Wars 2

Initial disclaimer: I read this suggestion on Reddit before the official forums were active, so please note that (a) it is not originally my own and (b) perhaps it has already been suggested here.

If not, here goes: Create an option for Fast Cast Ground Targeting, so that ground targeted abilities fire on key up, not key down. Upon key down, the targeting reticle shows, and upon key up, the ability fires. As is, all abilities trigger on key down, which is great for responsiveness, but this minor tweak will allow for very fast ground targeting, with the reticle, without the need to double tap the keys or click (which I often find to be buggy and slow…).

In other words, when you press the key down for a ground targeted ability, the reticle appears, and when you then release the key (key up), the ability fires. This is different than current Fast Cast Ground Targeting, which fires immediately upon pressing the key down.
