Hardcore Ironman would be a very welcome addition to the game.
I strongly agree that exp rates should be the same as on regular ironman.
After all, if you die - you are reverted to regular mode so makes perfect sense if you wish to carry on playing.
The Ring of Life is a fantastic suggestion and would help a lot.
Perhaps, there is a way to think of getting the 1 death at Zulrah per day or something to that effect if at all possible.
