How to fix the combat system

Combat got changed so drastically in 2016 that there is no way to make both 1.8 and 1.9+ players happy. So I propose a new solution. Add a gamerule to minecraft worlds called "OldCombat" which can be set to true or false. This would mean that average players who don't really care can have the new combat system, which works fine for everyday survival, but people in the 1.8 pvp community can have the old combat system even in the latest updates if they choose too. Also, since many 1.8 players don't like the way hunger works in 1.9+, there could be a second gamerule called "OldHunger" or something like that.
