I find it irritating that when I do a refresh, the same opponents that I just rejected will show up again very quickly. Often times one will show up in the very next set. This is absurd. When you refresh, you’re basically that you don’t want to play against any of those opponents. There should be at least 24 hours before they can show up again.
BTW last night I had an offering of as a ‘weak’ opponent who was level 1000, pvp rank of 37 and all troops were mythic and very powerful; hardly a ‘weak’ opponent. I did a refresh and that very same opponent showed up again in the next set as a ‘middle’ opponent.
