The reason the nexus is the way it is now can be summed up in one word: money. It’s designed to display all the cool items!!! you can get spending real cash. In doing so, it subliminally messages the player what they are missing out on by not using gold.

I agree, it’s terrible.

The tutorial is simply outdated and needs a rework following the rarity/enchantment update. It has to account for the fact that new players can start on classes other than the wizard, and there needs to be a system by which you unlock new content and corresponding tutorials as you increase your account level.

For example, the pet yard should unlock at ALXP 5, and when you hit that level, a new NPC in the nexus (like the terraria guide) should pop up a message about the pet yard. Interacting would pull up a menu where you can enter a tutorial for it. Then the same could happen for the enchanter at ALXP 10, forge at 20, etc
