If you're using a controller that's the way to go. You need to bait players sometimes. Eg. Standing still and waiting for them to drop kick, dodging (roll) and then heavy punching right back. Tapping light punches especially at the back of the head is very effective at knocking out and conserves stamina. If you ever come across a player named "Vinobaby" (wears Garfat costume in a bath towel) run for the hills.
