No. The ring was competitive with the bracers, and better when you had the right situation. The new PF hands are really strong, and the scorch belt is actually useful now. The helm is only good on burst AoE, it's probably below the new gloves on sustained cleave.
This nerf to the bracers proves Celestalon is a fucking retard. The proc rate was too strong, and there was a huge potential for massive variance in DPS due to RNG. Instead of fixing that (an icd) they nerfed the damage so now it's much less worth to cast even with procs.
