I just want a weapon with imo are the best subs and specials, the disruptor and bubbler. Oh wait... we're getting two new weapons with it, the tri slosher and mini gattling....
Anyways being a Custom Jet Squelcher, I would much rather have the bubbler over the kracken, even though like someone above said, that the bubbler is put on short range weapons to balance it out. While a disruptor is a very good support sub, I could just never get rid of burst bombs, because with proper damage up, the jettys ttk is really reduced and with bomb range up, you can throw burst bombs even farther than the jet swuelcher itself, which really makes up for the ttk at it's max range so
Jet Squelcher:
Burst bomb and Bubbler
The default one is fine with ink walls and inkstrike (really good for splatzones) I think of the default jetty as helps you not get killed and the custom one as help you get kills.
