So Vanu got their audio overhauled, and I personally love the new sounds, but I was wondering if/when the TR and NC will be getting the same treatment.
You're doing it wrong. You want to be going DAKKA DAKKA DAKKA And even then, it may not be enough dakka.
Bah vanu sound revamp isn't finished yet. They haven't change the ugly sound of the comet (which is the same as pounder and falcon).
