Just to appease the absolute cesspool of humanity that is people like OP lets go all out on pedantics and be unreasonable AF.
They should release one identical the real launch, limit internet to 128kb/s just to really hit that nostalgia button. It should demand dial up too. If you have a fancy modern internet connection it should block all access to classic servers.
To access via anything above dial up speeds they should require validation via bills that in the year 2005 you had better than dial up. Then it should require that you as the player are capping your internet to the 2005 speeds you provided bills for. If you were the insane person paying hundreds for a dedicated 2mb connection you have to restrict to the same speed to access.
They should also confirm your age and limit you to similar playtime. If you were in school no access to login between school hours, period. It will just say “login attempt blocked our nostalgia review notates you were in school at this time of day during original release”.
Definitely no PVP ranking until post BWL just like the true vanilla experience. No battlegrounds at all for the first 8 months. No Arathi basin for 11 months, just like the true experience. No honor for any pvp at all for 6 months.
