I have the set bonus from the new primeval pack on my storm. It's coming from my pet and my mount. However, when I enter places were no mounts are allowed the set bonus goes away like the pet pavilion and the drains the bonus goes away so I end up losing damage in the process (The mount is equipped before btw). Is this intentional? Nothing like this ever happened with the ghulture and the bonus seems to go away when I get off the mount to enter a fight as well.
I have also been experiencing the same issue. Doesn't matter if it's pve, pvp, whether I'm doing a fight inside a dungeon or on the street of unicorn way, which version of the bonus I have equipped, the new stat bonuses from the primeval mount just doesn't work. I would hope this isn't intentional as many people, including me, have bought these perm mounts because of the set bonuses. Even with that being said, the set bonuses from the mounts are applied visibly to our stats when equipped but then don't apply in battle so it truly feels unintentional. But hopefully this is fixed soon because I was excited to upgrade from ghultures.
