Seeing as you here you commented on LVL 50 HM FP, pretty sure it was safe to assume you didn't read it. He is not ************ about lvl 50 at all he's annoyed that on a lvl 34 FP NORMAL LVLING MODE that people are skipping all trash and being jerks about watching the video's. Wasn't trying to be a D*ck before but i can be now if you'd rather it like that.
Before Level 50 this phenomena is seldom seen. I am leveling a Commando myself and I have done full clears everytime I joined flashpoints with no one in the group objecting, all participating. This issue is much more prevalent at level 50.
