I'm a new player and I wouldn't have played the game if everything was free.
I've been enjoying learning about the game and trying things out even when it involves some grinding. (Yes, I found it fun to sell recipes on AH, to spend merits to earn some inf early, to learn about enhancement converters. And I can't wait to run TFs or whatever to earn more merits and inf once I hit 50.)
It's never been my cup of tea to cheat on a video game to make things easy or free.
It's also been really, really fun to learn about different types of enhancements(DOs, SOs, IOs...) and about how to build a character.
If everything was free, I wouldn't have needed to learn anything because I would've just bought attuned enhancements already and stopped caring.
A build wouldn't have mattered neither because I can always replace enhancements for free with no risk. It would kill the point of some system like alt builds and respec, and it would also make it significantly less important to put lots of thought on planning a build using Mids.
Your claim literally invalidates the whole point of playing a video game though. Even playing as a hero or a villain you created is just an illusion. You're just clicking buttons to interact with your CPU calculating numbers and your GPU displaying stuff on your screen. You know that, right? I don't understand how you can have fun playing a video game while having a such view.
