Waaaaay more than an hour.
The bm hunter one took me about 56 tries, average attempt was 8 minutes.
But I mean, it’s like doing heroic/mythic raid, high end keys. It’s SUPPOSED to be a challenge, not a give me mog thing.
Again I agree it needs a nerf, since then we had artifacts/legos/WAY more secondary stats, but you can’t go overboard.
And this is from someone with over half of the weapon mogs from legion.
