In short – not enough people have the booster maps to make havng them permanently in the rotation a viable option. Doesnt matter if all XDC have them because there may only ever be 5 or so XDC on the server in an evening and the cannonfodder who make up the rest of players haven’t bought it. So when a booster map comes on = server death.
I thought EF went down quite well on a Tuesday and Thursday when we ran them (except for the ‘tards who change teams to be on the Euro side). Maybe we should start doing that again and make sure we let enough people know in advance.
Psycho Al and Scary Snowman have the booster packs, as do several other regular players. Although I think running Armoured Fury is a bit too optomistic at the moment, even if it is a better add-on.
