I'm thinking more RP of the death than last words but, still..
Heros should get one last message after they die. Options restricted to 'Roleplay' and 'Everyone in this region'. 1000 characters max if worried about verbosity or to focus the mind of the author. One-turn time limit. Normal RP rules apply with extra guidance on the compose page if deemed necessary.
Yes, many may be crap but that's true of any message and we live with it .. but .. there is far more incentive than any other message to make a hero's last words good, inspiring, memorable, tragic, moving or otherwise remarkable. I suspect the good:bad ratio will be higher than any other type of message.
If nothing else if someone has been working on a years-long story they should have a chance to bring it to a conclusion in-game rather than hoping someone reads their wiki page.
As for last words, unrealistic in-game, maybe (let's face it; choosing whether or not to be able to die in battle is unrealistic) but might be worth it.. some examples of what we could hope for..
