Even with Spell Density set to ‘Essential’ it is extremely difficult to see what is going on in melee. With the upcoming (terrible) range reductions to some melee classes, that issue will only get worse.
Between the Frost Mage casting Frozen Orb, Paladin’s dropping consecration, and numerous other spell effects, it has become almost impossible to see small ground swirlies and other such boss and creature mechanics.
Please, please make the Essential Spell Density setting actually be just that. I really don’t need to see a Frost Mage’s frozen orb or a large number of other classes flashy spells. What I need to see is what the creatures are doing.
