I knew that anytime rewards are suggested for anything other than raids/dungeons, people protest it for some reason. I don’t understand it but I’ve come to expect it. 
Yes and hardcore leveling would be its own type of challenge. I’m not sure what your point is here.
No problem. I can explain. You said if people actually enjoy the journey of leveling, why does it need rewards? This is like saying if you enjoy a meal you don’t need to add salt. Just because something is already good doesn’t mean it can’t be better. And if you have the ability to take something you love and make it even better, why the heck wouldn’t you?
I litterally mentioned a hell mode. But really adventure mode should still get rewards too for the time and effort people put in. You know, just fun cosmetic stuff. Maybe a title like, “The Patient”… if it doesn’t already exist.
Also its a game. Not a job. Gamers don’t have to prove themself worthy constantly. Its okay to just mess around and have fun, you know?
