Ok, to be more specific:
In Mando Raiders do you really think getting to a point where the bonus boss can do absolutely nothing to your group and you can safely kill him is just using the environment to your advantage? I definitely don't think so.
I am not playing to gear up and jump into NM Operations, I play these FPs to have fun. And it is more fun without exploiting, that's my point.
After 4 wipes on mando raiders bonus boss due to enrage (1 dps on campaign and another on tionese), I suggested "let's stay here, he can't touch us".
Kicking players (with the associated drama), skiping the boss or quitting the group is less fun.
