Flashing effects all types

I come with a QoL question today.

It's unbelievable the amount of actions causing a flashy visual effect around the player: desynth, leveling up, crafting, and so on... I find that really annoying. At peak times, in main towns, it's impossible to find a summoning bell that is not surrounded by flashes in all colors and all directions.

Of course, we can retire to an inn room or map to an empty town, but well, if we need our GC or/and mats from again a different town (like Idyllshire that has no market board), the back and forth are a bother and rapidly expensive.

Therefore my 2 questions:
1. Is there really no settings allowing to turn off all those flashes?
2. Are the main GC NPCs (mats, missions, squadrons) nowhere else than in their base towns?

Thanks in advance.
