High levels that speed run the land of opportunity missions are complete dicks.
Speed running the starter missions for low levels completely ruin their experience. Nobody cares that you can rambo the shit. Let the low levels do their thing and have fun, once they're finished that, it's a slow burn from then on.
Also looting all the bodies while there's a chance low levels may loot....not cool, at least fucking wait and observe the room before you loot. Ffs.
