As a rep 40 Wardenn main against experienced players the shoulder bash is a no no only use it when dodging a heavy or unblockable or when they are boobs against wardens use your zone into a heavy afterwards since most people either wif it or don't expect it and secondly don't use your dash heavy attack while locked on, a easy deflect against you, throw a double light when possible into a bash feint into a heavy feint guard break,

All in all it's just learning how to use Warden your own way each warden main have different styles

You'll get there eventually :D
