The NM did not agro but other things around still did agro while fighting.
Honestly the patch makes it sound like an individual does not need to interact with the NM at all for the rewards. Sounds like the server kills enough NMs, then the chests for everyone get upgraded the following week.
This is exactly the way it's supposed to work and I'm perfectly fine with that, server effort vs individual effort. It's potentially nice and I think it suits well the gameplay approach of Limbus (no instancing etc).
I'm just concerned that if the only reward is a "chance" for someone to obtain something on the following week and they're this annoying to kill... well, it's likely not goin to be enough motivation to even bother.
They should
AT LEAST drop the amount of currency you'd normally get from a normal mob in the same wing of the same level.
Getting absolutely zero nothing nada niet paired with the fact they're annoying to kill, isn't gonna work well with the motivation required to even bother to kill them.
Are the NMs claimed by the party that's fighting them like traditional mobs or open to anyone in the zone to fight them like domain invasion
The latter, it's clearly written in the patch notes and was mentioned in previous communications by SE as well.
Anybody can join at any time on them.
