CD tracker allow you to know who is the best kill target and for cc/interrupt who got what.
You can have it and still be bad at death trap/blind for example or hit a target with all Def cd up if you got no idea how to use it but in fact it’s not bad for the game imo.
I agree with above weak aura make the game so much easier for sure but like irony said most of beginner/noon overload their screen and handicap them self with too much stuff.
I used to be dependent of add-on but now I barely use anything, and still can deal with offensive cd without add-on just need to look around.
The only weak aura I use is for stuff like death mark or shattering star and dh modifier (forgot the name) cause you are dead if you don’t react to that. And earthen wa no need more imo.
