Is there a stamina change I haven't seen?

compromise

I haven't played the game properly in a while so there may have been some change I can't find but have they changed stamina in relation to attacking the body?

I used to love it when someone constantly threw heavy hits so I could work their body and drain their stamina quickly but it feels like unless you're at the stage of rocking someone from a body hit that it does nothing to their stamina?

Used to feel good whittling away at someone's stamina but now going for the body feels a bit pointless
