Current problems with the regen
Current regen is fine when you fighting someone but when you are not it takes you 1 minute and 15 seconds total (+-75 seconds) to heal from half a heart to full (10) hearts. Making you wait quite a bit till your next fight as well as making it harder for you to streak and encouraging running.
Past suggestions about it
There were quite a few suggestions about FFA regeneration (most targeting the cleaning problem) such as: give regen after a kill, instant heal to 10 hearts after a kill, etc. All of them failed because of a few reasons the main being that the people who are cleaning would just kill the person with the low hearts get the regeneration and then kill you.
My suggestion to the issue
FFA tracks when you are in combat and when you are not. How about giving regen 1 or 2 to the player while he's not in combat and take it away when he either regenerates to full hearts or enters combat, if this suggestion was implemented it might reduce the amount of running in FFA as well as make it faster paced as well as more enjoyable. Don't think it would change the cleaning problem that much tho 
How it would work
After you kill a player you still have the normal regeneration till you get the "out of combat" message in chat (about 19 seconds later). After that, you receive regeneration 1 or 2.
- Regeneration 1 would heal you in about 40 seconds (from half a heart to full) with the 19 seconds combat time, in about 21 seconds after the "out of combat" message.
- Regeneration 2 would heal you in about 26 seconds (from half a heart to full) with the 19 seconds combat time, in about 7 seconds after the "out of combat" message.
To Java players
If you play CubeCraft java FFA please let me know if this would work and help the java server too!
Please let me know your thoughts on this!
Credits to Modulo7 as he also talked about something similar to this a year ago.
