Having level 12 experience with a warrior from long ago, and a level 20 experience with a hunter who seldom used Raptor Strike, I can't recall something.
STRUDELLLLLLLLLLL! AHHHHHHHHHHH!
(Sorry. Listening to Mann Gegen Mann by Rammstein currently.)
Abilities that are On Next Melee are, obviously, not instant attacks. Instead, they replace the next melee swing.
And that is where I wonder. Abilities that are instant attacks make the main hand swing. Does that mean that it's possible to hit Heroic Strike and then an instant attack (we'll use Hamstring), and then it will instantly do the damage of Heroic Strike plus the extra threat of Heroic Strike plus the damage of Hamstring plus the snare of Hamstring?
Also, while I think there's no global cooldown upon pressing Heroic Strike, does the global cooldown happen when the Heroic Strike takes effect?
From there, if the first question/scenario doesn't hold true, can one activate Heroic Strike, use Hamstring, and then Heroic Strike would go off on the autoattack after? Or does pressing Hamstring un-activate (word?) Heroic Strike?
STRUDELLLLLL---MANN GEGEN MANN!
