Flares (Handheld) as currently implemented in game are very limited and feel frustrating to use due to having a fixed shooting position, where you can't adjust the range youre firing at all, beyond maybe kneeling down for a very slight difference.
Enabling a way of aiming them, by either moving the camera and the flare moving with you, or adding sort of range settings that automatically adjust that angle such as on launchers, would be perfect for these. This would potentially increase their use, and be of great help to the honest players that don't turn their brightness to max on their graphics card for free night vision.
I would be interested in knowing if there is a reasoning behind this, if it's on purpose.
