Never Ever click on "Find a partner"
I am sharing my experience so that other summoners won't do the same mistake. So my prestige is around 4800 and I am in 13m alliance and I have been reaching 7500 points without much issues. Today I decided to use the new feature, as they call it, the "Find partner" button.
I selected the holy trinity and click on the button. Next second I was inside dungeon 5, with a player who had spidy classic, ant-man and Gambit (4* 4/40 of course). I was shocked. Next moment he took the mystic path without even asking and got kod on the first fight. I somehow finished the room with all the links up and concluded the dungeon. Ended up with 150 or so points and now I can't even use the trinity team without spending 120 bucks.
So guys if you are a skilled player, don't fall into this trap.
