I'm not taking sides here, but let me tell you what I did as a player gm for another game to give you guys perspective how it worked (gotta be careful here not to breach my NDA, lol) The player gm's were usually players with lots of experience with the game. They'd handle submitted tickets that were not important/critical enough for the actual GM's. Like, if player claimed a quest was bugged when he just didn't know how to complete it. If the player was stuck in some odd place and needed teleporting. If the player had made an rage ticket because they were upset, we'd handle it If a mob spawn bugged, we'd handle it. General, mundane stuff like that. All the other tasks we could not or were not allowed to handle, we'd escalate to an actual GM, like bugged quest rewards/other inventory related issues, reports of players abusing other players, etc. We did not have any power to set bans on players, etc. Also, applying for a player GM was not as simple as applying for, let's say, SWTOR beta testing. Without going into detail, let's say that games who have player gm's, usually have pretty efficient ways of weeding out the bad ones, but I'm not saying a single bad one couldn't slip past the process.
