Enemy levels in the current PvE subevent seem bugged (or use really strange design).
The levels change even if you don’t play. And in all directions. I made some notes, packs were 119/119/136/155/155/230/167/230 after I made 1st and 2nd once. Then half an hour later 135/126/115/177/154/230/169/230.
Going up after I played is one thing, but without? Like they were reflecting other people’s matches mixed in. But even for that some going down is weird.
If any of this is by-design you should have announced it in the rules.
I agree this event is certainly bugged as it seems to work in a way to completely discourage playing it.
I suggest it’s better to submit a ticket to mobilesupport@d3p.us in addition to (or instead) of posting here, as it seems they take those a bit more seriously.
The difficulty of the missions gets adjusted in response to the performance of all other players against those missions, as well as your performance in PvE.
