Guild Wars 2

Ranger Greatsword skill number 5; Hilt Bash.
Skill it not hitting at listed range of 300.

Tested on flat terrain in the mists by DPS trails waypoint.
Tested by moving Ranger so its character model (human) foot is inside the targeting reticle of a golem.
Selected the golem (so it was targeted) and then Insured 300 range by hitting a single keybind to make the Ranger dodge roll back (300 units). Upon completion of dodge roll use Hilt Bash.

The skill does what it wants. Sometimes it will hit the golem and sometimes it will not. When hilt bash fails to hit the golem, usually you can still hit it with the full auto attack chain so the golems hit box is within 130 range.

Assuming that Hilt Bash makes the Ranger leap foward 150 units and then the damage portion of the ability has a range of 150 (melee range) units there is no reason why the attack should ever fail to connect during my testing.
