Too much visual clutter during boss fight

Hi,

Just had to try 5 time to beat the Act II boss with my Electro Ranger.

Main trouble was last phase when circling to avoid the boss attack and on map AoE, it became increasingly harder to actually target the boss because I keep losing track of my mouse pointer with all the cluster fuck of special effects, especially as colorblind. Cost my 3 more tries than it should... I can't fathom what will happen with Death penalty and one try map...

This isn't a "fix" per se, but there's an option to change cursor size. I made mine bigger and it's much easier to keep track of.
