Catalyst is buffed, but it's so badly designed it's like multiplying zero by whatever in hope that will change something.
Top and Middle traits line are good with combinaison that are not 2 handed. Especially D/D because it has access to all aura easily and is really mobile. But do not expect to benefit from your jade sphere, because it's stationnary, small, will not generate enough energy and be busy enough to never activate them even once. You'll probably do a better job with tempest or weaver at close range with far less hassle.
Or you can take your favorite staff, get the bottom trait line and be an AoE backline support turret. Just take arcane and water, spam your attunement, water to heal, occasionally go into fire to make some damage (eventually take the spec elite so you can make 2 meteor shower back to back every 90 seconds lol) It's too bad staff is trash now and that others spec can support and do actual damage better than you.
Or you can take your favorite hammer, get all the drawbacks of other weapon (i.e not being able to benefit from its jade sphere, having to spam attunement to be somewhat useful) with even more drawbacks.You will have to always move because you are litterally paper, outside your jade sphere most of the time, because you have basically no mobility otherwise.You'll have to make sure your sphere (of hammer 3) is always up when you attack AND be in the right range AND switch as soon as you must even if you didn't burn all your weapon skills or you'll miss dps (because obviously, there are extreme range difference on this weapons) It's already 3 extra things to monitor just for ONE skill.
You can't use top traits well because there are no obvious way to gain aura (earth 4 doesn't count 'cause you lose dps) Or maybe you know your combo really well.
You can support your mate at the front line with the bottom trait line but now they all have the same problem as you since your jade sphere is so small, at least they can survive better.Lastly, you can use your middle traits, but now you just have to wait to escape an attack or use air 5 and earth 5 since you can't use air 4 (you'll lose dps).
With hammer, you'll probably do a better job with another spec or weapon combo and your support is laughable next to other spec. On the plus side, if you take the spec elite, you can spam Air 2 back to back if your target is stationnary lol.
Your hammer 3 should be a class thing, not a weapon skill, and should damage your ennemy whatever your range, the jade sphere should follow you everywhere and have no energy or no cooldown. Then throw your hammer away and forget it.
