The really weird thing is that the last couple times I've endured the horrors of Rabnasty the groups have been able to one-shot Hashmal, but wiped to Mateus and Rofocale of all bosses, mostly due to insta-wipe mechanics (and one sudden mass-afk wave that got everyone slaughtered almost instantly, which was incredibly bizarre). Although, when I think about it, I think in all the runs I've done of it there was really only one time Hashmal wiped the group. But at the same time I used to be able to get through entire runs without a single wipe. It's almost baffling how much the quality of groups has been lately, to the point I actually dread running it at this point.
