Flooding an area with a dozen uplinks has become a common strategy to guarantee territorial dominance of that location, and also creates a balance problem particularly in Domination. It can take forever clear out all the drop uplinks, and you would likely be killed by a newly spawned enemy before you could destroy all the uplinks. Some would suggest the use of flux grenades, but the area of effect isn't sufficient for eliminating multiple drop uplinks like 15 meters apart. Because of this, I believe drop uplinks should not be deployable within 100 meters of another friendly drop uplink. This would ensure that no spot is ridiculously covered in uplinks.

When you try to deploy a drop uplink, it should not deploy, and a message informing you of the proximity limit should appear on the screen to inform you. The alternative would be to have it deploy, but get immediately destroyed, but I imagine it would result in many unhappy mercs trying to set up their drop uplinks without any intent of abusing the system. If possible, players should be able to see a ring representing the 100 meter radius zone of friendly drop uplinks on their HUDs so they'll know where they can't drop their drop uplinks.
