Annihilators Grenade Launcher

[Sotales]

How do you get the Grenade Launcher to proc when using a heavy weapon? It says to use a basic attack, but as soon as you use a heavy weapon, you get a special attack that doesn't seem to proc Grenade Launcher at all. I even have the Grenade Launcher talent on my hotbar to monitor the cooldown. It never procs when using a heavy weapon, but when I use the Shoot talent (which is disabled when a heavy weapon is equipped) without a heavy weapon equipped it works fine. Not sure if I've explained this clearly enough, but I hope you get the basics of what I'm asking.

Use Shoot Luke...

But the shoot button changes to shooting your heavy weapon. I have the same problem with not being able to take off a heavy weapon without spending a turn.

Well, probably GL not working with heavy weapon is by design.
But not being able to switch between them without spending a turn is bad, bad, bad-bad-bad thing.
