You can definitely hit confirm 1, 2, 2. With Rep, you really need to have your opponent playing defensive, also know when to get in. Need to be good at hit confirming with Rep, if they block 1, 2, 2, try slide instead of force ball, if you have meter to spare go for EX dash then keep the pressure on. Rep has good pressure if you know how to do it.
Basic I know, but I'm kinda busy atm (:
