Minecraft wiki entry for Best_biomes_for_homes, associated text: On multiplayer, the Plains biome has both some heavy pros and some heavy cons. It is very easy to build defenses due to the flat terrain, and it is hard to be ambushed when at your base. However, the base (if at surface level) is easy to see. This means that enemy players/scouts could find a way in. If you settle in a plains biome, it is recommended that you make some tall walls to keep enemies away. Alternatively, you could build above or below a pillager outpost, and the pillagers would act as a natural defense. Before settling in a plains biome for a long time, you will want to have gathered a substantial amount of wood from the nearest trees so that you don't have to go back and forth between your base and a forest.
