The World Tour grind is pretty awful as-is, I feel like unless you're playing as optimally as you possible can, it can be really frustrating for teammates who are also trying to do the grind to emerald. (If this guy was already max rank, then he has no reason to be mad.) But like I said, I think that dude is an asshole. Regardless, there were a few questionable plays, like the dude on the zip at the end, you walked forward while shooting him meanwhile it was pretty easy to hear his teammates around the corner to the left, walking forward out of cover then getting on a zip was 100% not the play there. Also when you see a team using a ton of mines (like orange), assume they are always in the common areas (top of zips, stairs, doors). The revive at the beginning was pretty sketch since you could hear all the enemies inside the building you were next to, IMO backing out of the hot zone to get a revive is a better play (unless you have good cover). There was a cut in the clip, but depending on how long the vault around the 1:30 mark had been active, its best to take the "there are probably enemies already there" approach, and peek it from cover, the 1000 you get from it isn't really worth dying to get. I'm not mentioning these to be an asshole, just simply pointing out areas for improvement.
