Tbh when they mentioned Stasis as a new Element I was under the impression new weapons/enemies and abilities, so far there's only been on Stasis related weapon. I get there's some boundaries, lore wise, on why we cannot infuse Stasis to some weapons but it would be nice since elements don't really affect PvP so there's no worry there and if there's new Stasis enemy types then there would be more variable for PvE tactics. Ahh well, it is what it is.
