Hard Core on Retail.
My guild thinks I am nuts, but they support my efforts.
I play Hardcore on Retail Realms.
As a player with not so great health I am aware that sooner rather than later I will depart this planet. It is what it is.
I have played this game for 20 years with a few breaks here and there.
I was never really comfortable with the implementation of the Spirit Healer in the game. I think it is kinda silly.
If I cannot come back after my demise, why should my characters? I feel that they are a real part of me. I get emotional with them sometimes.
Then Blizzard created Hardcore Realms in Classic. If you die it asks you if you want to try again. Your character is gone. You start over.
Years ago some friends and I decided to level characters using the Ironman scheme. Only white gear, no professions at all. no AH. Gear only from Vendors. There were other restrictions and the level cap was 60. None of us made it to level cap but we had a lot of fun.
Playing Hardcore in Retail makes you pay more attention to what you are getting your character into. It can make you a better player. You might be forced to learn your spec just to stay alive.
Level cap is 80 and there is some challenging content in TWW for this type of player.
If you are looking for something different to do give Hardcore in Retail a try.
You just might surprise yourself. Above all, have fun.
