Your methodology is flawed because it’s not about skill for a large part of it it’s about the random cards you choose and what our levels of those cards happen to be and the random draw of your deck. I’ve beaten some top players, literally top ranks in Multiplayer and top rank in the event, and then have a losing streak with bad luck on draws. For example in the last event right before the system decided I would only get 5 medals I had a bad run of 4 losses in a row but right before that Imwon 4 out of 5. Your system has almost nothing to do with skill. If you gave everyone the same cards you could possibly argue that but the cards aren’t the same and the matchups are not well balanced.
On top of this once the system changes you to 5 medals you almost might as well not play because you cannot make progress and you can’t go on a significant enough win streak to change it. Why should I spend gems which cost real money to have your system ruin my game. It’s time to admit this system is just another way for rich to get richer because if you have all or most of the units at 17 you are much more likely to win than to lose no matter how good your opponent is. This drop to 5 medals is insulting and needs to go away. It’s not about skill it’s about streaks and those aren’t the same thing. For that matter if it were even somewhat consistent it might make sense but those of us playing see no transparency and no consistency in the system. This is literally the only PvP game I’ve played where the reward for wins and losses is just a mystery to me. The rest look at relative team power and give awards based on that. Beat a team lesser ranked then you are get a small award, beat a team higher ranked then you are get a big award. Play more, earn more. If you don’t want it to be about number of games played but about “skill” then why allow ticket purchases at all? Why not just have a set number of games everyone can play?
