I don't know if it's considered bad form to post in an old thread, but here goes.
My Revenant is dual-wielding swords, and most of the sound effects are missing while fighting.
OR
I hear them all at once after the enemy is dead.
Is anyone else experiencing this? Sometimes I hear a few sounds while fighting, but they don't seem to be synced with the abilities, and they're often faint and hard to hear.
