I replay stuff all the time. Especially during live tournaments and a caster missed something, I scrub back to the point, watch it at a different speed, then hit live again. Or if I go to the loo and don’t want to miss an important fight, pause, loo, scrub back a little to the beginning of the fight, then hit live.
It’s so basic. Any tournament organiser that’s twitch exclusive, I don’t watch and just wait for the highlights.
