Does Diablo 4 have a skill diversity issue?

destructoid.com:

Over the years, “Action RPG” games have evolved quite a bit, adding more and more player customization with each new entry into the genre. Diablo 3 released in 2012 with over a billion unique build possibilities across all of its classes. Hit ARPG Path of Exile has been constantly adding new abilities via its unique skill gem system for almost ten years.

As we began to learn more about Diablo 4 leading up to its release, just one week ago, it quickly became apparent we’d once again get a massive amount of potential builds. With five classes each with their own unique skill trees full of active and passive skills, the possibilities seemed endless. But now less than two weeks since the early access release of the game, it’s starting to look like Diablo 4 may have a bit of a skill diversity issue. Let’s take a bit of an analytics look at the situation and try to determine if things are as bad as they seem, or if this is just an early exaggeration.

Thanks to a nifty spreadsheet compiled on the /r/diablo4 subreddit, we can see what skills players are using.  This sheet shows us what percentage of skills the highest level players in non-hardcore Diablo 4.

We obviously can’t draw conclusions based on this limited sample size of the top players. But this information at least gives us a glimpse at what may be some pretty lacking skill diversity. For leveling, some skills are better than others but most are viable enough. This data is based on the highest-level players, so these builds are intended for the all-important endgame.

Let me start by saying my main class is a Sorcerer. Even though I’m not at max level, I’m over Level 50
