I am in the stage 7 arena. Myself and everyone I battle has high 2k low 3k health dinos. In comes astrozzz with a 7k Apatosaurus. We all know the outcome to such an unevenly matched battle. My 3rd dino was finally able to take him out and guess what he follows with? A 5k Einiasuchus! Come on! Reminds me of the playground bully! Stay in your own appropriate dino health level/stage arena!
