unannounced arena change?
I'm wondering if others have experienced the following ...
Starting 3 or 4 weeks ago, it seems that (roughly) every 5th arena refresh brings up an unusually week set of opponents:
my specific experience: I'm sitting in Gold 2 with a decent but far from exceptional team. Most refreshes bring up a group of opponents that are all or mostly much stronger than my team. But every 5th refresh (again, roughly) I get one with a mix of weak full teams plus single hero intentionally weak teams. Thus with regular refreshes, over the course of the day I can usually win 25-30 matches (50-60 gold medals) despite having a relatively weak team for Gold 2.
It's clear that this is not merely random, as I see very few refreshes with intermediate results - it's mostly very strong sets of opponents, with occasional very weak sets of opponents.
