I'm not sure this update would affect kill steals. It would overall make the FFA server more balanced for everyone.I mean I am pretty sure I would own you both but whatever...
Yeah I guess kill steals would really ruin the game :(
I asked a few cubecrafters who were found on other 1.9 FFA servers, "Why do you choose to not play on CubeCraft's FFA server?" and they all gave similar answers. They don't like having to wait around for health regen between pvp encounters. Most people play FFA to practice, and it would make sense that people get annoyed about wasting so much time waiting for regen.
Killsteals are already present in FFA, and is something you will always find in almost every pvp gamemode. I can tell you, the community does not like them xD. Most 'cleaners' are heavily targeted after being witnessed stealing kills, and bullied out of cleaning again. Overall its not a solution to the kill-stealing problem, just a solution to make the FFA server more balanced and win back the players who are going to other servers instead. =]
Thanks for the feedback ♥
