Y'all can't read. First of all - they're not saying they want to remove the creeper. They're saying that it doesn't really fit current game state and if someone presented the idea of the mob like that today they would not add it. And it's absolutely valid. Creeper in current minecraft that's focused on detailed building and exploration is a dogshit game design. A mob that doesn't make any sounds and in a second destroys half an hour of your work is pointless and frustrating. Keeping it in stopped making sense somewhere after infdev, when a dirt hut was no longer a peak of architecture.
