Atleast I hope it’s a bug and not a secret nerf. You can now be stunned, feared, immobilized, crippled, chilled, while in mistform. Same applies to vapor form. You are no longer an invulnerable mist as the description says. You can be CCed and have new conditions applied to you, including torment and poison. The skill is totally useless now since it no longer protects you and just locks you out of using your other skills.
And i’m not the only one experiencing this. https://forum-en.gw2archive.eu/forum/professions/elementalist/Ninja-nerf-in-this-patch/first#post2590300
