i guess that they will create 2 servers like two dimensions ,well just like america, asia, Europe,africa or one half and the other half town will be same for both but map will be different
and after u reach hardcore lvls the achievement will be together or could be just like elite and normal maps

just select hardcore same way that u select elite maps
it could be like change charaters on the main menu options.




but i really thing if you change your main acc for a hardcore mode then u die and you are not available to spawn again, people that lose they progresse and also they cant pay plat for spawn if you character is delete ,all of you main archivement gone maybe 4 years of play lost people are going to leave the game.



or just could be like you select hardcore and the game reload with a new charater with the same name , archivement just with out pet ,items and exp, hardcore more could be like lvl up from 1 to 71 in normal = 1 lvl on hardecore.

but you will do what u have on mind, you will fine the way Good Luck!
