People groan but at least somewhat put up with skirmish because you don't have to do a skirmish run everytime you want to try for another aug (that and there are more close equivalents). Plus it's not even necessarily specific stats that make some of these capes so good. Some just stack so much good they become great. Look at rng with no augs it's decent but then with augs it can become itself +empyrean cape which is still good and even some snapshot which doesn't exist elsewhere in slot. Or run... combine augments with original stats and you get a cape great for DDing and tanking with 8 DT a bunch of acc, DA and mab. Bst is another example. Right now for bst pet capes you have to decide between stats like pdt, acc or att. With the augments you can get all 3 except that pdt becomes DT. Really you can make an argument for almost every cape and why it shouldn't be so frustrating to get
