It's been quite bad since EW (I think).

Many visual effects (VFX) that's been designed since EW launch (WHM's Holy I flashbang is a tiny exception) are made to look good from spectator's eyes, but didn't take account of the surrounding players' PoV. All SMN's summon attacks are like this: bright + blurry shockwaves placed above target's location. If you're a tank, well too bad! That SMN's going to blind you every 15s or so with all their summons!

Of course, that's not all. They later doubled down on this by adding more bright pillars VFXs that I really like to refer as "Satellite Beams" such as BRD's Radiant Encore, DNC's Dance of the Dawn, WAR's Primal Ruination, DRG's Starcross(?), oh dear the list goes on lol. Ignoring the conflicting theme (Why they all summon satellite beam lol), these bright pillars all goes out roughly around the same time during 2m reopeners which only clutters the visuals even further. And yes, AST's Sun Sign is also up there. Let's also not forget some cases where things like Asylum, Soil, and Gravity I never was an issue until they receive their radius buff!

Designing VFXs by assuming everyone would just turn them off is low effort, lame. At the very least I'd like them to tone down the use of motion blurs. It's cool once but they tire my eyes really quickly.
