I have been using the trainer successfully over the past few weeks. I'm probably not the first to do this, but thought to share. I use trainer to equip and train-up all the members of my community. It's fun to give each person a backpack, pistols and long guns, and beef up all their attributes. So everyone is kicking major zombie butt, and (maybe its my imagination) but it seems less people complain and I have less sick and tired people in the group.. guess they are having too much fun playing with their guns.. LOL... Cheers.
