My idea of how kits should be
Beserker: iron axe kb1 sharp 1
Full iron armor perm Slowness 1
Elf: punch 2 bow sharp 1 iron sword Full leather armor prot 2
Speed 2
Tank: Full iron armor Diamond sword, slowness 3
fighter: full gold prot 3: wood sword sharp 3
Orc: Prot 3 diamond chest rest of armor leather, diamond axe sharp one
hunger 1 (must continue to kill people to stabilize hunger, I think it could work)
You have to unlock kits with kill points:
Beserker: Free
Elf: 50 points
Tank: 60 points
Fighter: 50 points
Orc: 70 points
Since there is no advantage of kits, Everyone is happy! all that matters here is skill!
