I’d say the first grid square at the bottom left may have flattened out a bit because of the NPE. but really it only teaches you the VERY basics. i’ve been helping a new player through his first few days in eve recently, and the amount that the NPE doesn’t teach you is staggering. but most of it a veteran wouldn’t even notice because we take so much of it for granted. A prime example, just the other day he figured out that you can decycle your guns in order to change targets. before then he had just been shooting at each rat until it was dead and moving on to the next one (what the NPE teaches you).
It had never even occurred to me to explain that part to him because its second nature now.
The rest of the curve I think is still accurate, if anything it might be even worse now in some ways. There are more ships, many more valid meta’s, (as opposed to “just fly a rifter, you don’t need anything else”) more options available to newer players, and with those options more things to learn sooner in order to make educated choices.
Skill injectors haven’t helped the situation much anyways. skill points have never been the important thing when it comes to learning the game, but it can seem that way for a new player. before injectors you had no choice but to take your time training into a ship, and presumably, by the time you could fly something, you would have enough actual experience to not make a total mess of things (yes you still had the character bazaar, but its a lot easier to just buy 1 injector than to buy a whole character)
now though, you can take a day old player with a credit card and sit them in a carrier with no idea what a cyno even is.
