Is it normal that Diablo 3 is very easy

I started playing with a friend of mine and we got to somewhat level 20 and we started to up our difficulty from normal on up. (no idea what it's called exactly) After that we still noticed it was very easy and we went to the highest diffculty possible(Not the one you unlock at level 60) and it was still way too easy. We never die or get in danger. Is this normal in Diablo 3 or are we missing something? We're level 40 now. We played from level 30 - level 40 in the highest possible difficulty

Solution 1:

Here is a table of the difficulty and how it portrays to drops and monster health and exp.

This is how I usually play from scratch (new season and 0 paragon points).

• I start on Expert because early levels are so easy.
• I always start with bounties, I never play through the campaign. I recommend this because it's a great way to get rift shards quick and easy and you can use all of them once you get to level 70.
• If you have never played through the campaign and you are interested in it, it's fine to start with the campaign.
• Once I hit level 40ish, I usually have to turn the difficulty either up or down depending on my current items. If I've found a really good weapon, I turn it up. If I haven't found a good weapon, I turn it down to Hard.
• It's always a good idea to KILL MORE AT A LOWER DIFFICULTY than it is to TAKE LONGER AT A HIGHER ONE.
• Once you hit level 70, start rifting. Blood shards and rift guardians will be a great source to get legendaries.
• If you can skip Torment 1, do it. Torment 2 is a HUGE increase in legendary find and exp.

Solution 2:

yes, it is normal, after they updated the game they changed the difficulty settings, now you dont have to finish the game like 4 times to get to the hardest difficulty, instead you can adjust the difficulty to level up faster or at your own pace.
