I was thinking about more tactical mode, than just single intel run - multiple C&H.

On map there's a 5 symetrical goals (eg. flags) - two on both sides and one in center, or 1 on both sides and 3 in center, placed vertically. Teams goal is to capture this flags and hold it as long as it possible. Every 10 seconds of flag hold, team scores 1 point, so max 5 points can be scored every 10s. Match ends when points (or time) hit the limit.
Another funny idea is with spawns - players can CHOOSE spawn at their side near map edge (eg. if no flags possesed) OR around choosen flag possesed by team.
To capture the flag possesed by opposite team, you need to stay next to it for 10s.

This would make game more tactical and cooperative (when you choosing your spawn, you see on map wheres rest of your team, so you can choose less defended flag, or join the massive raids from flag A to flag B)

This of course can be done with 2-3-4 flags, instead of 5 - still better than just chase for 1 intel.
Optionally, one more rule can be implemented - block under flag = unbreakable, to force defensive building, rather than making long gay shafts leading down.

I know, that theres MANY things more important right now, than new game modes, but it's just a idea, maybe for distant future.
