Walling is about Patience, If you got Patience.. I believe you can win most of the spars you play. The best sparrer in the game, Sarah walls and gets high streaks everytime(which u could just complain about her delay) but she didn't care to wait 5 minutes every spar, She was Patient and went for wins, nothing less. I don't exactly like 5 minute spars personally, but whenever I wanna win, Ill be patient and run a lil.
