you said it's not hard to level up on free area but you suddenly switch from free area to challenge which require step by step walkthrough to unlock it.
you really should look at this from fair perspective.
i think we could easily understand each other if i said i didn't join the discord and getting extra knowledge there.
i literally learn the game by playing hence why i restarted my progress because i don't want to invest on training skill due to stats cap show up very earlier.
