D2 is an awesome, but not a perfect game. D3 is far from perfect.
Both games have their own flaws. Flaws, that exist regardless of whether peope agree with it or not.
Whether you agree with it or not, both games were designed with trading being a major aspect and the basic gameplay being an afterthought. Might have felt super skilled and difficult 20 years ago, nowadays it’s laughable and skilless.
Even freaking Reaper of Souls didn’t correct a lot of the decisions, that were clearly meant to incentivize trading. I don’t see skills having inherent power of their own, everything is dependant on the freaking weapon. It doesn’t matter how high paragon level you are, what awesome set bonus you have… you take away the weapon and you’re useless.
That’s an objective flaw in D3.
In D2 so many items are completely useless, it’s not even funny. And many were rendered useless due to patch 1.10 and power creep. That’s a flaw.
The rudamentary interface of D2, where the freaking stamina bar takes half the screen, having merely 2 skill shortcuts, having to swap with separate shortcuts, but having to cast everything with the 2 mouse keys and not being able to cast with the keyboard… that’s a flaw.
The way you trigger the World event in D2… that’s a flaw.
Infinite Paragon in D3… that’s a flaw… and that’s something most fans of the series will agree with.
D3 throughout most of it’s seasons was trash, that didn’t have much if any build diversity. Hell, not even all the classes were viable for high GRs during a season, let alone various builds. That was a pretty bad flaw, that was persistent for many years since RoS came out.
Only relatively recently things changed for the better.
I could go on, but I’d have to write a freaking book on how many things were mishandled across D3. D2 certainly has less flaws, but it certainly isn’t without flaws.
The franchise needs to take what was good about the previous games. In D2 it was the skill system and partially the itemization. In D3 it was the interface, the smoothness of the combat and… sadly, not much else.
Both games are lacking in terms of how engaging is the gameplay. Again, might have seemed skilled back then, it’s rather lame nowadays.
And whether you’re willing to admit it or not, that was the direction the D4 devs said they were gonna take. The game being a slower paced, less power creep in order to not undermine the atmosphere of the game and the world to feel actually dangerous.
I am not making this up, it was literally in the presentation on BlizzCon, or in one of the blog posts.
And yes, the game might change direction as some people are no longer in the team and the game is delayed, but some of thje things – they did get right.
The franchise absolutely needs to evolve. The same old already feels very dated, let alone several years from now.
