Getting 100 wins on only a specific map is absolutely ridiculous. It's hard enough to get 100 wins in Frontlines as it is, but you want to lock the Field Commander set to wins on one specific map on a rotating schedule for maps. Once I learned it was only for wins on the Seal Rock map, I instantly lost interest in Frontlines and PVP in general. I wouldn't feel it any more or less of an achievement were it just 100 wins overall, but time-gating me out of the set just feels like a complete cop-out.
