Umm... I hear all of you saying horses, but when you use a horse spawn egg, you don`t always get a horse. And to me, horses are sort of OP in a chase and stuff, unless you have a bowand arrows.Sort of like a boat inwater PVP. Here`s my personal list:
1: potions of speed and potions of healthand regen. No potions that give give strengh or do damage or anything. Too OP
2:Enchantment bottles. Enough for maybe one or two levels, so you can at least enchant one thing
3:Iron armor. No other kinds, just iron. Makes it better than teir two, but not OP, like it would be if there were diamond armor
4:This is a temporary idea, if thought of as too OP, it can be removed. May be hard to program, but maybe a compass
that points to the nearest player. If it was added, then there could only be one per map, maybe two for forty eight player matches.
That`s it for now,I`ll add more ideas as they come
