Now I am making this thread to hopefully share some laughs in a positive way of course. Now what I am talking about for example, from Reach I am sure that Kat drove you off a cliff for no apparent reason once or twice. So I was wondering has anything like that happened to you in H5? For me in mission 15 solo on legendary of course. I was battling the knights in the room towards the end of the mission, the room with the man cannons and ramps and platforms. Well I was doing good only a couple left. I get close to the ledge to shoot down at a night. Well I guess Buck wanted to see what I was shooting at so he proceeds to push me off the edge right in front of the knight who of course slashes me once with the sword and kills me. Had to pretty much start the room over from a check point… I hate Buck… 
Oh and thanks Linda for not reviving me first and letting me die…
Both me & a teammate went down at the same time, pretty close together, with the AI positioned between us.
We both called for AI help up and it spent the entire cool-down period running back and forth between us without actually helping.
Just, walk towards me… stop, turn around, walk towards him, stop, turn around, walk towards me, etc.
All we could do was sit there and watch as the idiot AI frantically ran back & forth 5 steps at a time until we slowly whittled away into death
