This is normal? Play sole combats, win one and win 11 trophies, but… Lose 5, and lose 47, 50, 35 and 30… So there is no interest in playing 
@Killerdog, what you are experiencing is an unfortunate conundrum which occurs when you are repeatedly matched against players with lower current trophy counts. The mechanism for trophy adjustments is based on a ratio dependent on the trophy count divergence between opponents. I don’t recall the specific ratio, but if you beat a player with 200 fewer trophies than you, you will be awarded approx. 10 trophies. Alternatively if you defeat a player with 200 more trophies than you, you will be awarded 45-50 trophies. The inverse is true for losses. This quandary is one of many weaknesses attached to the flawed match-making formula.
[Edit: PvP Event Periods: Ludia continues to use alternative trophy counts during events. These counts are obscured and instead battle mode counts are shown. It is understood the awards/deductions during events periods follow the same pattern, but the relative event trophy counts are unknown. As such, this cannot be confirmed.]
I lose with a player with more trophies than me and lose 30 trophies. This game starts to be boring…
