We fixed the mass DCs, but there is still another issue which for now, until we can push a fix next week, can be worked around by turning on Disable Particles Master.
Maybe every class at once, but more likely a bigger portion at once. For example, personally I’d like to rework wisMod on priest, paladin and mystic to have more impact like the newer formulas for sorcerer and necromancer.
Already answered that here for the most part. PT was a good first step and will continue to improve, while we are also working on a more refined roadmap.
