When attacking, after clearing any AI and players that are there. It would be a welcome change if when interacting with the laptop, it would start a timer (ex. 5 minutes for smaller COPs and 10 minutes for the large COPs)
The attacking team would have to defend for the duration of the timer to successfully seize control from the enemy faction. This timer would give the defending faction time to mobilize and set up a proper counter strike.
Could create some more meaningful fights and slightly prevent vacuuming loot up during the fight if the COP is unusable for respawn and vendor/stash access during the siege period.
It would also stop an enemy from hiding in a bush to prevent laptop use. The timer would be able to be started regardless of if an enemy is still on the premises and the only way for the defending team to stop the capture is by interacting with the laptop again.
