1: Taking the fight outside the ring
The Attitude Era definitely took wrestling out of the box it had been confined in for years. Matches nowadays are just confined to the ring but fans of the golden era of pro wrestling will recall matches spilling into the crowd, backstage, boiler rooms and sometimes even the streets outside the arena. Who can forget the iconic backstage brawls and hardcore matches help during this era, not to mention the 24X7 rule for the Hardcore Championship and Stone Cold beating the daylights out of Booker T in the supermarket.
Fans miss the days when fights were unpredictable and could break out anytime or anywhere, be it backstage, in the locker room shower or even a local drinking establishment. Nowadays, the action we get is almost always in the ring and almost never goes backstage.
