Here are some of my ideas for new perks and updates to existing perks as well.
1.Update Pain Train to allow players to kick in or ram down doors instead of lockpicking them and allow players to do so to inaccessible doors as well. It would be great to be able to do that instead of lockpicking and it would be even better and funnier to see the gameplay footage of other players doing so just to be surprised by and/or outnumbered and outgunned by an enemy or crowd of enemies as they bust the door down.
2. Update Robotics Expert to allow players to revive robots that were killed in combat, either by them or someone or something else, provided that they sacrifice searching the robot to do so. That perk is a good perk but if it could be upgraded but if it let users revive robots and then command them it would be much better and cool to see players doing so in the gameplay videos on YouTube. I can just imagine someone exclaiming "It's alive!" as they reactivate a downed robot.
