There is something seriously wrong with how Gambit Prime registers Sentry kills toward the Locksmith medal. At the time of me posting this, while running 15 Sentry points, I have killed 263 blockers in Gambit Prime. I average between 8-10 blockers a game. Normally these are sent one-at-a-time, although pairs of 2 are not uncommon. I am the only one on my team killing them each time. Of these 263 kills, I have gotten 11 Locksmith medals. The current text states that the Locksmith medal is given to the Sentry who opens the bank for their team 3 times in a single round. I can go 5+ games in a row without ever seeing one of these medals, yet I'll open the bank around 6 times each game. I know I'm opening the bank each time because I play in a premade team, so we're all in open communication. I've noticed that it never gives me the medal if one side has a primeval, although that doesn't make any sense either... but what are the other conditions that prevent players from getting this? Either something is seriously wrong, or there are more conditions that we aren't being told. Thanks! [u][b]EDIT:[/b][/u] Unfortunately, I still never got an answer from Bungie or the community, [i]but[/i], I found out what's going wrong through some more testing. As it turns out, [u]all three blockers must be killed in the same life[/u]. The reason I was struggling for so long to get this triumph was because I was doubling as the team's invader, and I would confront enemy invaders so I could tag them for my team, which would sometimes result in my death. Unfortunately, there is no in-game indication that these kills have to be without dying.
