So sad that it is, the timebreaker and graverobber were patched so their insane speed trick are no longer working. Well, this means that just about any mission involving a sparrow now has an unbeatable time. The way I see it, 1 of 2 things should be done: 1. All mission times that involve a sparrow should be archived and the main leaderboards should be wiped seeing as how it's literally impossible to beat those times now. 2. A separate leaderboard or option for after patch 2.1 should be put up for all missions involving sparrows.
Now, it's not my decision but I felt like this should be brought to people's attention seeing as how such a major trick for most missions is no longer able to be used and that something should be done. If it's too much of a hassle to make a separate leaderboard or to archive all the old times I'd be happy to help out and/or make a google doc of all the old times for every mission and post it in it's own forum post for all to see should the decision to wipe all the leaderboards be the chosen option.
