Some classes are better-suited for newcomers

Blizzard teases there will be at a minimum, a major update towards the end of D2R Items July. That update will add additional features as well as the previously introduced class Change feature. This will let players transform their existing character into another class without needing to start from scratch.

Despite Blizzard's blog post offering the first details in regards to Diablo Immortal's plans post-launch, there is no mention of the fact that they have received feedback from players with the context of Diablo Immortal's highly criticized microtransactions and pay-to-win mechanics, that have caused a lot of angst in players' Diablo community. Even though microtransactions appear to be popular, Diablo Immortal has reportedly already made $50 million since the game's release.Your first decision upon starting is choosing a course, and unfortunately, the game does about as little as possible to give you a sense of what it's to be a part of any one of them. Aside from a brief description it's up to you to make your choice largely based on the look of the class.

Although you're able to make new characters but you cannot swap classes once you've made your decision, so every time you get into the character will be nothing if you decide that you'd prefer playing a different. (You can, thankfully, make use of the new shared loot box for moving items between characters. There's no more starting a session, dropping everything you have in town leaving, then returning with a different character in order for moving items.)

Some classes are better-suited for newcomers than others; Sorceress relies heavily Best place to buy D2R items on casting spells and mana, as you'd expect, and is relatively frail, making it more difficult for new players to play as a solo player in the beginning (although her teleporting ability can be an incredible lifesaver once get it).
