Clearly statements made by people who definitely did not play 20+ years ago. Leveling up by killing in the good old days was FAR slower than ToV kill grinding is today, especially with things like free Lesson to everyone now. Also you premise of less choice of exp is straight up false too. Back then quest exp was absolutely worthless, never in any capacity an option to level with beyond newbie levels. Kill grinding was the only way to level, so now we have more choice now in that quest exp is a real viable way to level like it never was before.
