In the early days of World War II, a covert military experiment turned Steve Rogers into America's first super-soldier: Captain America.Marvel Source
During the war, Cap served as a symbol of freedom and America's most effective special operative. In the closing days of the war, Captain America disappeared in an explosion over the North Atlantic and was presumed dead.
Decades later, his body was discovered trapped in ice, preserved in a state of suspended animation! Upon his revival, Captain America joined the Avengers and once again took up the heroic battle against evil.
You're gonna want opening strike maxed, quick block maxed, and an aura (spirited or encouraging). Right now Your build looks like you're trying to use bounce/bash but while your shield is bouncing you can't bash so you'll just stand there doing nothing the whole time. I would also ditch the two charges and use leap. Unfortunately right now Captain shield throwing build doesn't seem very viable in endgame IMO when you compare to a bash build.
