Blood happens if it's a legit cut, they don't blade anymore. They occasionally happen and the referee tries to clean it up, Cena v Lesnar had a fair bit of blood, Lesnar gave him a proper shot to the face lol
There's no reason you shouldn't, even if you watch it alongside RS
Just Google 'desirulez' if you don't already know about that site. They upload during the show and when I wake up 7/8 the day after there is always full downloads ready.
