Since I assume (and its already been mentioned) that people are referring to roofing on Espa and Slave quarters in particular, here is my (widely known) view.

Roofing at Slave quarters should NOT be allowed as in general it takes specialist knowledge to get up there even though you do not require a vehicle. The reason for this is not only because it frustrates new players who cannot get up there but also because (and has been verified by some members who have posted here) that in some circumstances when spawning on an officer, or when a beacon is placed there, it opens up a very serious glitch.

At the Imperial outpost on Bestine where you have a ladder running up the side of the building, I can see a valid reason for roofing, since that is easily accessed. That said, I would still prefer to see that cp radius reduced to negate the need to be up there except to provide a sniper perch.

Endor Strike Team - No roofing on the Outpost since that requires a speeder to access.

Same for the cp's on rhenvar where you need to utilise a speeder to get on various Imperial buildings.

I really really hate roofing at Espa even though others advocate it. As I've said, the reaon is simple, it can lead to a glitch. Gwynzer, since you know what I'm talking about then I would have thought you would recognise the need to prevent people being up there.

As I say Angel, the only problem I have with it on that map is because it can lead to what would generally be called cheating.
