Today, there were Wizards/Witches using Ritardando (bubble) on Karanda non-stop. First of all, because Pearl Abyss really doesn't tell us much, we don't even know if the "Attack Speed -50% for 10 sec." works on world bosses; my guess is that they are immune to such an effect. Secondly, the bubbling effect makes it near impossible to see where the boss is facing amid all the chaos, and this can lead to unnecessary one-shotting and player deaths. Regardless of whether debuffs like Ritardando work on world bosses or not, I think we deserve to be able to see the world boss and where it is facing clearly. So can you please provide an option to hide certain effects, like Ritardando's bubble, on bosses from other players? Thank you.
