if a point is in a building, then the entire building should be the objective
I have never once had anyone come up into an attic after me, even if I left the way up in tact.
If I threw a detpack down after myself I would be invincible in a few points.
Depends on the building.
If it has an attic, what stops me from climbing up a squad in there, with another friend, so we have 2 entire squads worth of people, and then blocking the door with a tank trap or somethin else?
Super easily exploitable.
then i agree with you 2, we could either close up access up there and remove attics from being apart of the point
I somewhat agree with this (depends on the building) just because it would stop rally points from being built in buildings with a control point if the entire thing was the point. Looking at you, Monastery Conquest A.
Or you could not make the whole building the cap point. 
there are already buildings that have attatics apart of the point anyways, they are C point and A point on chateu and swamp respectivefully
and those should probably get patched out. Bots are pretty good at staying in attics so you can get your whole squad up there and toss a detpack down behind yourself.
you don’t even need to throw a dem pack since if you prone you can dismantle the sand bag
Sometimes you can just climb furniture up, but that’s mostly Moscow
yeah i mostly play normandy where swamp’s A point and chateu’s C point are in buildings that count the attics as being apart of the point
