My feedback:
It is genuinely one of the least fun elite specs I have played so far, and this specialization goes farther and shows just how bad ele is designed at its core. The weapon itself feels clunky and slow, the animations are not anything special and the dmg is extremely lacking. The weapon/traits/skills have no true identity it's considered a brawler class but lacks damage, auras don't do anything special and weaver/tempest do both better while also providing support to allies via aura. The prettiest skill in this spec is the air 4 that channels a tornado other than that nothing stands out, and I'd go as far to say the augment skills and elite are actually... boring and center around using a sphere which stays in place and doesn't last long. In WvW those sphere's will be useless since you're constantly on the move, during livestream they mentioned how they're similar to engi gyros but unlike the gyros which move we have a stasis sphere which doesn't do... much at all.
This specialization shows how bad core ele is in traits and how the class needs help and reworks. Catalyst needs an entire rework to be honest, and I would actually be overjoyed if they switched the melee aspect of the weapon to something range since it's something ele fans wanted and needed. Every elite being melee so far is disappointing and does nothing to help the stack meta issue in pve but rather encourages mindless gameplay.
Beyond being disappointed not receiving either a longbow/shortbow which ele community has been hoping and asking for I wanted to have hope for the weapon and thought it could do well and bring something unique to ele gameplay and be a fun brawler type class that can provide dmg and be tanky similar to warrior but instead it is a low dmg/low survivability clunky elite which does everything worse than weaver.
