This is a suggestion that if the dome is down and the trapper isn’t being actively attacked, they can ‘maintain’ the shield by standing at the dome beacon and interacting with it. As soon as they are attacked, the ‘maintain’ ability would be lost.
It might even be something like a 1 second buff to the timer which can be activated every 5 seconds, if the Trapper can sit there long enough to activate it.
The purpose of this would be to give the hunters more time in the dome to track down hiding monsters, but not more time to fight trapped monsters. The dome gives some interesting nooks and crannies for a good monster to exploit, and I don’t want to take those away, I’m just looking at ways to give the hunter’s more time to check them all, without giving them a scanner.
Till then I’ll just stick to dropping a sonic spike with Griff after the dome.
