I would imagine the classic cash shop would be more close to how it was at launch which for the first year or two of original GMS was pretty much only cosmetic. There was no Auto Hp/MP and only pet auto loots which some might qualify as"p2w" but I think its more pay for convenience and dont think it falls under the umbrella of what most consider part of the egregious "p2w". The baseline tele rock might also have been in the cash shop but I cant remember exactly. Ap Resets, Exp/drop coupons, Gach, VIP rocks, loot box keys and buying of literal sacks of mesos with nx all came later. I can still remember reading a post from a Wizet GM sometime in 2006 where they stated they had no intention of adding p2w to the cash shop and that it would remain cosmetic only. Interestingly enough I still have a link to an article discussing when they first added AP resets for anyone interested https://tinyurl.com/55m2du8c If this is how the state of the Classic cash shop was for the first year plus, I'd consider that a huge win for players
i think i will try it to see if is the classic world is good or or not but i don't give my hope up so much. mostly because most maps will look different.
