That’s possible. Times were different then from what they are now. There was no possibility to respec in D2, for example, then. I would push for that, if I were a time traveler going back to 2004, and able to speak to WoW designers. I’d also advocate for shareable loot, such that nothing binded on equip or pickup.
Personally, I think that (and making things ephemeral [or have a shelf life]) would keep things interesting for the long term.
