For a game called "Puzzles and Survival," the stupid RNG their match-3 games have for their Arena feature would surely kill you. Their arena should've had an ELO system where you'd fight players with hero mights around yours but no siree! Once you placed your hero formation on Arena mode you're toast and should expect to have around 800-900 points just because the sharks are eating literally everything lower than 8mil. Stupid mechanics.
