I have spell density set to essential but i cannot see the swirly indiactors of the gargoyles in Halls of Atonment when they do their boulder attack, meanwhile streamers get to see swirly indicators for the same attack so why do i get handicaped ?
Ive noticed it for other attacks in other dungeons, im playing the game on hard mode because of some bug from blizzard
Check the “Projected Textures” setting which handles swirlies.
i have no idea why there’s a setting that turns off something that essential, great minds of blizzard at work
Either projected textures cause a strain on certain setups or people can turn it off if they’re feeling brave and want to dodge em without seein’ em. 
It’s for people that try to play WoW on a potato.
I remember when boss abilities and aoe spells used to have defined borders. Now everything is vague, transparent and undefined. I was amazed at these things we needed to dodge in Castle Nathria on Artificer Xy’Mox, it was called Rift Blast and it was just so hard to see, just some translucent white lines down each side where the blast was going to happen. Attacks like this are just getting harder and harder to spot due to how they are designed, funnily enough just as the player base is getting older haha.
