Volatile crystals should either make more sound or be more visible

My eyes are not seeing these before I die. My ears do not hear these before I die.

If the design intention was for the player to check every rare mob's mods for volatile crystals, then this is working as intended.

Absolutely. Died twice to them in one hit and could barely registered what happened and didn't see or hear anything except some purple effects right before I died.

+1. 95% of my deaths in maps are because of this or other volatile.

It's like these mods are balanced around us constantly running at 50% movespeed and spam dodge rolling the entire time we get in range of rares...
but then the rest of the game and easier mods wouldn't come close to even doing damage to us if we did that.

Honestly they seem just bad in general.

Even if you learn to recognize them. you then have to just wait around or something while they time out before looting.
