Guild Wars 2

This applies to skills like the engineer’s grenades and mortar, and wall-mounted cannon in WvW, where a physical projectile launches from the player to the targeted location.

At the moment, the targeting marker is always green, regardless of whether the projectile can actually reach the designated spot due to interfering terrain. It may be more helpful if the marker turns red when the spot cannot be reached.

Alternatively, the trajectory of the projectile should be shown so players can judge for themselves.

This would make it easier to use these skills especially atop balconies or walls with railings or other wall-edged structures; the trajectory of these projectiles tend to have insufficient elevation to clear these wall-edged structures when targeted at close-ranged targets.

In the case of WvW cannon, an example may be found at the south-west tower on each Borderlands map, in the cannon mounted to the west of the gate. There is a deadzone west of the cannon since cannonball is liable to hit the tower wall due to the flat trajectory. This is not reflected by the targeting marker, which shows green for that entire area.
