Please add a blinking yellow arrow over mirrorbacks (similar to the Barrows Brothers arrow) and/or give a popup when it spawns. It's extremely difficult to see and just kills you if you don't notice it instantly.
#Araxxor Mirrorback Spider Visibility

It also doesn't help that it's almost perfectly identical to the Bladed Spider so even when you do realize there's a Mirrorback you can't tell which spider to click.

tbh as much as anything else just making it render on top would be a big improvement. nothing wrong with tracking to the 3rd/2nd spider on diff spider waves so you're required to know when the spec spider spawns, but doing nothing until you can work out where the fker is is not fun
