Diamond generators spawn diamonds way too often,which makes people get Diamond sword and iron armor way too quick, so make it balanced, a third generator can be added which spawns emeralds. One spawns every one minute. So we can set the prices accordingly:
Diamond sword: 2 emeralds
Iron armor: 4 emeralds
x1 Deepslate: 1 emerald
Potions: 2 emeralds
In Faster Generators gamemode, from 1 minute it can reduce to 45 seconds.
Hope the admins consider putting this in game. This will balance the matches by a lot.
