Honestly, I've been enjoying Arc 3.0 on Warlock quite a bit. Maybe not as much as I have with Titan, but well enough.
The one thing that really sticks out to me is how bad the supers are. It feels like can do far more dps with weapons than Chaos Reach can do, and unlike Thundercrash, it takes a long time to use. Also, it still doesn't really refund any significant amount of super energy when you end it early.
Stormtrance, on the other hand, just feels worse than using Delicate Tomb or Trinity Ghoul for add clear.
I hope that these get buffed, but with TWAB after TWAB going by without a peep about subclass balance, it looks like Bungies not going to lift a finger.
Honestly, I'd love to officially hear if they have any plans on adjusting these supers, or if they're just planning on leaving them as they are.
