For those of us who played the original Diablo III on the PC and then switched to RoS on the PS4, what is the normal mode of progression? I beat the game on normal with a 50 mage over the weekend and then went to check out adventure mode on hard and I like that it gives me objects to do. Even found one of those rift keys which took me to an area to slay enough to trigger the boss. Should I be finishing the normal game on each difficulty, getting to level 70, or continuing to mess with adventure mode?
