I have tried a couple times. This is frustrating!
Ah boy, you’re in for quite a journey my friend. Just keep running Heroic ICC on every high-level alt you have and eventually you’ll get it, hopefully.
To put it in perspective for you, I’ve seen people with well over 500 runs of H ICC and they still haven’t gotten it yet. But don’t let that dishearten you, because you could get it at any time, even your very next run.
Godspeed brother, and good luck on collecting.
I got it on my paladin at the same time he got exalted from the rep you get from doing ICC.
You might already have it in your bags, you just can’t see it.
Took me four hundred.
