Delerium on every map = depressing

So in order to map optimally i have to apply oil to all maps to get more rarity etc.. but this turns every single map into a grey scale smoke filled delerium map. its really lame. You guys went thru all the trouble of making a beautiful game with amazing graphics and environments. but i have to essentially make it all grey all the time super depressing to play. would love to see the real map and colors OTHER THAN GREY......

This is indeed an issue. Personally, I prefer gameplay to "efficiency" so I add Delirium rarely.

Delirium + wisp effects + abyss = I'm blind
