Eh, because it doesn't matter? They were obviously maxed/stratted out to the gills+nukes and so on. And let them have their glory.
Such things as that don't mean anything to me because I, like many others, don't play like that, nor does it interest me. I don't play on 4/8 because...well, what does that prove? Something to others, nothing to me. Everyone has their own comfort zone, and by that I don't mean "cotton wool covered space where nothing bad happens to you". There are no non performers, there are no upper echelon players. There are just players.
Give me a well written AE that I have to get through at -1/1 because I really want to see this story over a Kill Most/All ITF Speed Run 4/8...because that's how I play 🙂
That said, echoing above, if a PUG of 8 could do that on any random day, now THAT is an issue.
