I’m not sure if they do this for other classes, but I’ve played exclusively a Thief since launch and Infiltrator’s Arrow/Shadowstep/etc like to say “Out of range” a lot.
It can be detrimental in the middle of a fight, so I think it would be a lot better if, when you shoot Infiltrator’s Arrow with your cursor past the maximum distance, the skill should still activate and it should still send you as close as the range of the skill would allow you to get to your cursor’s position.
This allows perfect 100% use of the range of the skills, and a lot less spamming the number key and tantalizingly slowly moving your mouse downward in the middle of a heated fight trying to get mobile when your class places EXTREME importance on mobility.
