Unfortunately it feels like I thought it would when I saw the teaser image.
Hammer is so so so slow even compared to staff (the only other two handed weapon that Ele has), same goes for the F5 skill.
Since I brought it up let's talk about the F5 skill a little more:
it feels that the field, since it is a projected field by the Arcane Sphere it should be able to follow you around, static like that when the profession is both ranged and melee it is not good especially if you swap between the two.
The duration of Hammer 3 is really laughable. If you have to fight off a mob and use any other skill instead of H3 on all 4 attunements (with all their cooldowns) you don't have enough time to chain all 4.
Also the damage done on full celestial is very very very low even with all Elemental Empowerment traits.
Weaver is a faster elite spec that feels more rewarding to use both in power and in rotation.
I'll try it some more today and come back to you 😀
