Here is a creative thread where folks may post their ideas about how Supers in the game could be better in terms of animation, style and application to the character. This is NOT for taking about damage done, speed of execution, etc. This is purely about style and continuity.
Just my opinion: Superman’s “Super” (Animation/Design Wise) is weak. Shazam’s has way more style. It would make more sense if he Knocked you a much further distance and punched you through a planet. Flash’s Super also has a flaw. If he ran around the planet and hit someone, the opponent would go much further on just momentum alone. It’d be better if Flash ran around Earth, punched them, ran back around, Kicked them, (the animation would be faster than the current “planet revolve”) then just did some speed punching or “ping-pong” the opponent on stage.
