Night vision is not necessary, you get night vision on all of the night maps and their is no need when it is day time :)i personally want CERTAIN Potions ONLY
including
-Speed (could replace god apples, OP)
-Night Vision (not that op only in games like space where it is dark)
-Splash Healing (Op Mode and expensive enough)
-Regen (even though this kit exists)
What is a big NO!
-Invis
-Strength
-harming
-Poison
but to me the only potions i see getting added is speed I and Night Vision
so its a 50 50 to me
