I suggest to have the pest control minigame portals barrier drop after each kill on the current assigned portal.
instead of waiting 15-20 secs for a portal barrier to drop after each kill when there are atleast 10+ people at pc, portals die within few secs due to high amount of damage
also instead of getting 1-2 minutes pc game we can get lot less , which is more fun and less boring, waiting 20 secs for a barrier to drop after you kill a portal in 2 secs is really boring and makes people give up and get bored really fast.
