Sorry if theres a thread for this already, didn't find any with search.
The current valour system in siege requires you to fight constantly against enemies. If you really want to get it, theres no time to stop for a minute to destroy a door or gate. (Unless map requires it of course). This is a shame, since usually destroying those really helps your team.
Thus I suggest that attackers would get a small amount of points. It should be so big that you still have some sort of chance to get valour, and at the same time so small that only smashing dem doors doesn't give valour and it wouldn't encourage people to pointlessly destroy them. And obviously defenders wouldn't get any points. I believe this would make valour whores, who often do the highest damage, to help the team more. Also smashing the doors is really boring and I think many people avoid doing it.
