The “find a partner” feature in dungeons should allow both players to see each other’s champs.
I can’t count the times that I’ve loaded up lvl 7dungeons with an appropriate team rating and the other player is using champs well below the suggested team rating and can’t get pass room 1-2. While champs rating doesn’t equal skill level it does usually say something about account progression. Idk the algorithm that’s used to pair summoners but as it currently stands it’s horrible. Pair summoners with similar team rating or at least give us the option to see their champs so we can make the decision on if we want to take the risk.
