It's not that people hate Halo. You enjoy whatever you want as long as you don't force it onto us.
However, most of the community think that people should be more creative. Why make something that was already made? (Aside from features, and the game's base [Build stuff])
People should be using their creativity to make something new. Something we haven't seen before. Most of us know what the Energy Sword is, it's been around for years. Maybe we don't want to see it everywhere anymore. Why not have an energy sword that's unique, and has a different style of usage?
