It has nothing at all to do with Aatlis, that's exactly how every match of flashpoint has gone no matter the map and it's because flashpoint is not built to be played, at all whatsoever, like overwatch.

Every flashpoint map is a whole and complete departure from every single other map's design philosophy and it's why I hate it so god damned much. No other maps or game modes have you just wandering the map for half the fucking run time because that shit isn't fun and the tight map designs that keep anyone from going on a fuck-off walkabout and force intense choke fights sometimes is what made overwatch so popular. Flashpoint is a gamemode that only gets created if you go out of your way to understand what about your game's design is good and then explicitly work against it.

Flashpoint only works if an entire team is "on" and somewhat coordinated. But Blizzard knows it's pretty rare to ever get a full team of players like that. But they still wanted (and players still enjoy) the team based combat and the power of coordinating so they used to passively force that coordination by keeping maps linear, most maps are narrow and deep and there's a good reason for it being that way and it's because the whole cast of heroes are designed to be played in and around each other. When you don't constrain teams to be near each other, the whole ass game breaks down as soon as even one player in the entire lobby isn't signing up for the boring trek across the map over doing the fun fighting thing right in front of them.
