No..... no guns.... this is Minecraft not call of duty... if you want guns look for mods
Minecraft should in my opinion have a little bit of everything. Whats wrong with having technology in minecraft? I like minecraft should have everything, machines, magic, potions, guns, RPG style bosses, RPG style dungeons, RTS style pet and mount control, time travel, portals, aliens, spaceships, demons, ghosts, angels, gods, mobs, gardening, shopping, battling, wiring EVERYTHING. JUST EVERYTHING. If you don't like it, don't use it. No idea should be rejected simply because people arbitrarily feel its un-minecraft.
More mobs: Tigers, Snakes, Lions, Bears, Turtles, Lizards, Birds of MANY colors, Vampire Bats, Rams, Deers, Giants, Dwarfs, Horrific Demonic Mobs 100x more scary then endermen, Skeleton Mages, Skeleton Warriors, Wither Skeleton Mages, Wither Skeleton Archers And many more.
Dogs: You could get many types of dogs from poodles to hound dogs to siberian huskies. You would have a chance of getting them when breeding wolves. Some would have more health then others and some would do more damage and some would be faster and some slower .
A Better Cat System: Add lions, tigers ETC. and have a chance of getting various breeds of cat when breeding them together.
Machines: Industrialcraft mod style machines with some differences to fit in minecraft better.
More Types Of TNT: Fire TNT, Nukes, Charged TNT, Dirty Bombs ETC.
Flying Pets That You Can Ride: Dragons, Gryphons, Giant Dragonflies, Ghasts ETC.
Magic: Staffs, Wands, Spells, Buffs ETC.
Changed Potion System: Allow potions to be renamed and dyed in an anvil thus hiding its effects (Be fun on servers to make a poison potion look like a speed potion ETC.). Allow Multiple Effects to be put on a single potions. Allow more levels of potions, Like for instance speed 5. Allow potions to stack to 64 and splash potion not to stack because it could be OP.
More Potions: Nausea, Water Walking, Water Breathing, Jump Boost, Aqua Affinity, Haste, Blindness, ETC.
Well Optimized Cubic Chunk Format that would thus allow for a sky limit at about Y: 11, 000 and an underground generation limit of about Y:-1000 (Though As you went deeper everything would just be lava) (In order for caves to still generate it might be a good idea too make diamond ore a little less common as caves at diamond level would be much easier to find and be much larger. If you got about say Y: 7500 then you would be in space and you're breath bar would deplete as if underwater. Respiration enchantment can slow this down.
NO THIRST BAR...EVER!!!
A Pet Bed That Pets Can Respawn at. (Not working in hardcore mode of course)
