I've taken a break from the game for various content related reasons, and when coming back to play through 6.4 content the amount of visual noise in encounters designed is very apparent, specifically 'The Twelfth Circle'.

Mechanically the battle isn't difficult but to actually see tells through spell effects combined with those of the boss frankly just make my eyes sore. This isn't good design, and has been a mounting problem that finally has reached a point where it has become a negative experience.

....and yes, I have had other players spell effects turned off for years. This shouldn't be a requirement to actually see the battle in the first place.
