No Crimson Fist are broken in survival. If you go against one with your main team in survival, beat the entire team save for the main who keeps shielding and he stalls you out; you both lose in a sense. Sure you'll win the fight, but you lose your entire team in the process even though you've clearly won. Shields from Earth Mains in Survival should be nerfed considerably, or at least take away the,"When time is up, you can win but you'll lose everyone on your team," nonsense.
