For me, I don't want to ever see any quest giver outside of the tower/farm/ planet hub.
I don't need zavala for shit.
I fought crota, where the fuck was he?
I fought Atheon, where the fuck was he then?
Skola's? Yep, done it without Zavala's help
I fought Oryx... yea, keep your lame ass in the tower Zavala
SIVA..... Not only did I kill it, I even killed the legendary guardians that it had taken over.
Yea, Zavala can lick my ass. He isn't a badass, he shouldn't be considered one. He is just a dude that yells at people every now and again, and helps Holiday deal with her Daddy issues.
EDIT:
On second thought, Zavala, shake a leg and get me another tank or 3. I am tired of fighting gods for you fucks without some useful artillery
