Ability to adjust Visual Effects

Can we please have a feature in the Options to adjust VisualEffects for example like

Visual Effects of Enemy Skills: Slider
Visual Effects of Own Skills: Slider

and basicly reduce the Opacity of the skill at max 50% Opacity if its any crontradiction with Game mechanics.

I am just watching the steam of a Melee player and, me myself playing arsonist Minions, seee almost nothing of any indicateors of enemys. This would help!

Almost all the builds I played in the endgame transformed the battlefield (especially in the boss arena where it is important to see the ground) into something shiny and messy, where you can barely identify enemy moves and/or scene mechanics... simply impractical to play properly, especially for hardcore characters, where there is no second attempt
