[Suggestion] Death Mechanics Suggestion

In a recent developer Q&A, there was a brief discussion about polling new death mechanics. Here is my idea combined with some features implemented in Runescape 2:

• Starting at level 1 prayer; you recieve the old standard 2 minute window to collect your loot.
• For every prayer level gained, 1 minute is added to the timer. Up to a total of 1 hour and 40 minutes at 99 prayer. (This is open for discussion for balancing issues). This would give high level prayer a purpose.
• The timer would be displayed on the screen along with the world that you was connected to at death.
• Gravestones returning could be a possibility. Could serve as a possible goldsink to change the model of the gravestone.
• Hardcore Ironmen could have a different model/colour and the grave could be visible for other players to view for a longer period of time but no loot would be obtainable. It could also show total level and experience at the time of death.
• After the time expires all loot disappears as normal.

Sorry for the lack for image/formatting; this is my first suggestion. If you have any other ideas related please share them below. Thanks
