JasPythooonimo, just remove the spire and put the cp on the roof. much more simpler, no need to put so much effort into something that people generally don't want.
The sightline from roof to that ramp thingy under the window room is too long. If RED has a decent sniper he can take pot shots all day and make it incredibly difficult to cap. Plus that sniper can't be jumped and has a healthpack right next to him.
There's nothing wrong with moving the cap point behind the roof, a simple spire will do, no need to make it overly complicated.
put a piece of sheet metal on the roof to block the sightline (i.e.) badlands spire, gullywash spire, process spire...you get the point
