When I played D2, there was no respec’ing at all. Honestly, it made for painful character development as you couldn’t invest in the shitty early skills to get you through the levels. Instead, you had to suffer through the levelling process only putting 1 point in these early skills because they were prerequisites for your final skills. Then you finally hit level 20 or whatever to unlock the skills you want and suddenly you can start spending skill points. Then if you wanted to try a different build, you made a whole new character and went through all that grind again. But it was the only option we had, so we lived with it.

D3’s system was entirely flexible and you could switch at any time, especially after they added the armoury to store complete builds. I think I got spoiled by this and now I don’t see any good reason that we shouldn’t just be able to switch easily between farming and pushing builds.

D4’s system is halfway between. You can fully respec your character… but they’ve designed the UI to be hostile to it. It’s easy to refund all your skills and reassign them, but it’s impossible to refund all paragon points except by clicking through them all one by one. It feels like a big step backwards from what we had in D3. All this does is discourage experimentation in builds. Even if they don’t want us to have an armoury to easily manage multiple builds, why on Earth haven’t they provided a “refund all” button for paragon points when we have one for skill points? The cynic in me says “so they can put Scrolls of Amnesia in the in-game store”.
