Here's what I suggest.
Two different kinds of war.
PK War: Both groups agree to a PK war, and they make a roster of both sides, and of who is dead/alive. When someone dies from either side, their death is marked, and they can't participate in the war until it is over. Once the war is over, a 48 hour cooldown is to be administered to allow the groups to regain themselves and allow them to RP.
Long Term War: Both groups agree to this, it is kinda like what is going on currently, but heres how it goes. Both factions agree to a LTW, they shoot it out, and after an attack happens, there is a 24 hour cooldown, making it so that both groups can only attack ONCE a day, giving groups time to plan strategies that are most efficient to eliminate the other side. This continues till either side surrenders or both come to terms of peace.

There is no any 'cooldown' in gang wars.
Once someone is dead in a war which must be for a very strong reason, he is not allowed to create nonsense reasons to kill and continue the war.
Or coming the next day saying 'We're in war' or 'His family member attacked us, he should die' are just bullshit reasons and it is mass deathmatch.
If you want another war you need a strong reason too. What is happening daily is based on unreasonable reasons.
The problem here is every group think they win if they kill the other side, which is completely wrong.
The groups themselves should change what they are doing, and be creative with their role-play.
Review and read these, they'll help.
