I just get irritated when newbs in bullet storm dont even try to get team skill shots. Its one thing if people try and just screw it up. But when a team challenge says, "Bullet Slide", and I see the same idiot kicking him every round, yeah it gets annoying.
Nothing to rage over, but I will leave groups if they continually fail at the same level. (Just thought id point out im in the top 1% of the PC leader boards in bullet storm).
As far as halo goes, some times the antics in reach with the crappy map design get annoying, but nothing as far as players are concerned, na, no rage from me there.
