As a goblin warrior after you use the racial Goblin Jump, you are locked out of Heroic Leap for ~5 seconds. If this is an intentional interaction, a debuff indicating the remaining time left until Heroic Leap is useable again would be the very least that could be done.
This is a very annoying bug because when trying to plan movement in a fight you always need to Heroic Leap and then Rocket Jump. If you accidently Rocket Jump first and then need to Heroic Leap you are unnecessarily punished and die which is incredibly frustrating.
This bug has been around for years and I test it every year to see if I can finally race change back to my favourite race without being randomly punished in fights for using my racial.
