Basically the intel as it is does not make for fun games. It is not fun when you take intel after diggng for 10 minutes to stealthly enter an enemy base (which is being well defended by the way), only for them to be able to chase you down with intel bacuse you are given away by intel sign on map...
What needs to happen is whenever a player picks up the intel it is removed from the map as a marker and cannot be seen where the intel is untill the enemy is killed and it is dropped.
Also as mention in other threads the intel should be allowed to be dropped by the player carrying it, this would allow for lots of tactical game play combined with above idea. Imagine preparing an ambush with your squad, one of you then getting intel back to ambush location, drop the intel to lure the enemy in as they try and protect it from capture.
A intel return option is needed for both teams, so when an enemy dies after taking intel away from base, there needs to be some way to return the intel to your base.
It can be instant return if one of your team stands over intel.
It could be a capture bar like in the conquest game mode, you and your team have to stand over intel for x amount of time before it is returned (the more the faster it progresses), this would add tactical play since you and your team would have to defend intel and guy/s trying to re-capture intel to your base.
Last idea would be allow you and your team to pick up your own intel but you can only move at 50% normal speed while you try to return the intel to base. To stop your team moving intel around or trying to help enemy by taking itel to them etc, have it so that no one on your team can move intel when it is within 100 or so blocks of your main spawn/base.
Feel free to add more ideas and feedback to the above ones guys.
