Ascendance runs aren’t 1:100. They’re probably 1:4 but still subject to rng.
You also don’t NEED the right GA on your mythics. It just helps a bit around the edges. The difference between the right GA and the wrong GA isn’t that significant. Thats like arguing your self found 18/14 griffons in d2 isn’t good enough and you have to have a 20/15.
Didn't say the ascendance runs were 1:100. Just mentioned I got 3 myth uniques from them and the others from bosses is what I meant to be more clear. Definitely want the right GA on my Harlequins to be cooldown reduction. Without it i cannot spam teleport still has a tiny delay.
