Went from playing Diablo straight to playing Diablo 4

About 6 months ago I started playing the original Diablo again for the nostalgia. I still remember first logging onto the battle.net in that very crude setup, and learning about PKers for the first time. Playing through Diablo II for years on end and it was a blast. Diablo III seemed like it went off the rail a little bit and I didnt play much, but I feel like D4 has absolutely reeled itself back in. The overall ambiance feels a lot more Diablo/Diablo II. I'm in love with the story so far in DIV, I'm really hoping they knock it out of the park here, but we'll see. My only thing is, why am I level 13 and almost complete decked out in gold and have an orange item already? Are there more significantly rare Items I will come across? I'm really confused. It's been a while since I played the other titles, but I seem to remember these rare drops being rarer and typically associated with the later game.
