There isn't much more to say—Arcanist simply emits an excessive number of particles, which can completely obscure your vision unless you disable them through mods or do /pq off (even that doesnt properly work).
It's already challenging enough that the meteor is so disproportionately large, effectively forcing players to use third-person view when utilizing Psychokinesis. But when you add the overwhelming visual clutter from all the effects—Poof, Explosion (Emitter), Cloud, and that black one whose name escapes me—it becomes far too much.
Please consider reducing the particle output from each meteor. Even if the individual particle count per meteor doesn't seem high, their cumulative effect quickly becomes visually overwhelming.
