This is the erason I run certain classes for HC.
No claymores or betties and no CP.
There are a lot of people trolling others and there is a high chance you kill team mates with explosives.
For HC I'll choose scorestreaks that will not kill my team mates.
It's the risk you take when playing HC
So it can kick you if a player is destroying your own equipment? (Makes a second account for this.) Jokes, i'm not a douche but that stinks if that's so.
I've never run into any trolling so far that I have recalled unlike in previous titles where people would follow me and shoot to give out my location...Even though I would be running around the map.
Actually though the only troll thing that has came to mind so far for me is someone took my CP back in the first week of Blops2 lol, he threw a shock charge on it and got it faster then I could.
The deaths scroll is usually called a killfeed.
Unfortunately trolling happens in Hardcore and even if you have ricochet it won't stop it. What I find slightly strange is that spawn killing is deemed not okay (I don't do this as YT videos that show this seriously bore me) because it is not considered a fair game, yet you can effectively boost for the opposition by destroying friendly equipment?
In MW3 you can exact revenge on people destroying your equipment to get SitRep Pro by throwing a C4 on to a Trophy System so when they knife it the C4 explodes.
i've said it before and i'll say it again
it should be a bannable and reportable offense when people on purpose try to mess with your gaming experience like that
it got big in mw3 with the SUK vids on yt it seems, and since then it's gotten really annoying
atleast you can avoid them through their GT for being an unsportive player
