when did ww fight supermn at superhigh speed they were just fighting they weren't going all dragonballz and moving there hands real fast you couldn't see them.
And you fanboys make it sound like ww always hade access to the speedforce since day 1 if pietro came to dc universe he would of reach it way before her.
In dragon ball z they stopped using the blurred fists animation technique after the freeza saga and just animated the character normally. Would you say they no longer had super speed?
Besides we've seen them do that enough times to show they can fight at superspeed.
Also its a fair bet that when two characters who have vast super speed are flying along at faster than light speed while fighting each other that they're using their speed.
If we saw Superman actually speedblitzing Wonder woman you'd have an argument.
