You dont understand how powerful having a fourth shot is. You're complaining about the decreased timer while using the helm. You feel that other subclass specific exotics don't "nerf" the super or some other aspect of the subclass so Symbiote shouldn't decrease the timer. What I'm saying is there isn't a similar enough exotic that it can be compared to to make what you're saying fair. Having a fourth Golden Gun shot with almost no downsides is incredibly powerful. "We had to give up our exotic slot!" There was no Gunslinger exotic that compared to the Symbiote. You weren't giving up much.
