The freeze duration is solely a PvP change. Funny enough, there are certain enemies in PvE that have cold snap as the freeze type they do, and the freeze duration from that is also reduced. Aside from that, there is virtually no difference in how Shadbinder plays, and it is still easily better than the other two stasis classes thanks to its aspects and, dear mother of god, four fragment slots compared to the hunter's current two and the titan's current three. The super lasted way too long, even for PvE, and it is incredibly easy to use and very strong thanks to the lack of effort needed compared to the damage it does. I say this as a Titan main, and it honestly feels like treason.
