Your progression can be destroyed if you play with friends who are higher level.

I joined my friend's party while I was still in Act 1 and found myself viewing the Act 4 cutscene, pop up in the Act 4 hub town and was even able to join the fight of an Act 4 boss (and was killed in one hit)

That's called boosting and it has been around since D2. People boosting level 1s in Hell Baal runs were pretty common.

True, but what I meant was that in Diablo 2, you had to go through certain quests and what not to progress and even if you joined your friend's game, you were still limited to what act you were on (not counting normal, nightmare and hell obviously).

In Diablo 3, I joined a friend's game and it let me into Act 4, showed me the cutscene and I could teleport to them in the action even though my character's progress was only still in Act 1.
