I've seen sometimes that my teammates, particularly NBs, spent all their time sprinting around in high speed, dodging through groups of enemies, and constantly switch targets. Every time I went to help them, they're gone in a blink instead of trying to finish what they started.
Checked their scores and they're not bad but not really good either, feel like they're mostly wasting their own time. What's the whole point of this playstyle aside from looking cool and be very annoying for teamwork?
