Outside of raids this class is going to be painful. Inside of raids the lighting field providing quickness is cool and the boon trait for jade sphere means you can basically run a dps who provides quickness. I personally didn't play a ton of this just because I am farming for mats right now and wasn't that interested. Looking at it objectively there needs to be a significantly reduced auramancer vibe. That was tempest's thing and let it have that. All those traits that try to be auramancer can go into giving the jade sphere faster energy charge, making it mobile - actually the cool way to make it mobile would be to have it do something when you swap attunements and that thing pulls it to you (fun grandmaster idea), making it do new things and being an active part of your build rather than a meh tool.
Personally I found the 2 on hammer to be really fun but the 5 skills need alot of work. I would agree the autos feel a tad slow and with the fire and lighting ones being ranged there isn't much reason for it. The earth auto is cool but I think the spikes either need to hit harder or apply bleed. I would also love to see a flip over on the jade sphere to dump its remaining energy (after you add some traits to make building it back up easier) and do something cool and flashy. Thats about the only place I would want to see an aura on catalyst.
Water is just bad, with resolution only giving condi reduction the boon is meh and the skills just feel bad, the two is a rip from hundred blades but doesn't hit as hard and doesn't make sense (you can do that but you can't swing the hammer normally that fast really?). The four should be an aoe heal like most ele weapons have and the chill that is being applied everywhere is literally worthless anywhere other than pvp or niche moments that I can't think of off hand.
The utility skills are just disappointing overall. I honestly can't even remember what they do and outside of the one that gives barrier which I need to switch to earth to get I don't think I used them for long. If you want an augment skill type I would go with utilities that amp up the jade sphere for a little while. Give it some life and flare for a little while with each of them.
- The water one could make the sphere clear condis and gain energy for each one removed.
- The fire one could do some damage or something
- The lightning could be a cc around the sphere that charges energy based on how many it hit.
- The eath one would give barrier and charge the sphere based on how many it hit.
- The heal could be a pulsing heal around the sphere with a flip over to detonate the sphere for a burst heal
- The ult fully charges the sphere or gives a damage amp to nearby allies based on how charged the sphere is.
For all the people who say it can't do open world content I would suggest taking a look at your gear, I was playing around in verdant brink with no problems outside of the jade sphere being immobile.
