Minecraft isnt just a game about building. You have to think about the pvp community, which is essentially 50-60% of the minecraft community. If MineHeroes were to update their mechanics to anything above 1.8, the server would instantly die due to half of its population being pvpers. You can bring up the argument that there are more skyblock players than faction players. However, you have to take into count of the alts, and the players who play both; like myself.
