The random part is really annoying, it sucks so much when you put so much time and effort into your collection, and then you cant finish it off just because your unlucky. ive played my char for a good 4 years now, and ive yet to see any of the random drops from summer festival :/
I dont mind their being some rng in it, like if i could just do the instances as much as i wanted or something, but having blizzard saying, you got X number of tries, if you dont get it in that, its just to bad for you, really sucks.
atleast if you could do it as many times as you like, you can always give yourself the fault for not going for it hard enough.
Also, i cant post on US forum : /
