Roofbases were making everyone base in places in which they often removed their way up to, in theory forcing people to propclimb to base up there. The expansion saw this rule change, which had been planned for quite some time. There's plenty of empty rooms on even at 70-80 players, which could easily fit a decent defense system. Ground bases are often allowed by admins (especially at the mining area, etc.).

They were often ugly, caused lag, and people who didn't build them well often ruined it for others.
