Why are people starting to flame at each other over the situation? Different people have different methods on obtaining trophies. Some do it naturally and others need extra help from their friends, it happens and there's no point in hating on each other about it!
Personally I think it's also ridiculous. In almost ALL multiplayer games people boost for trophies. For those who thinks it's cheating. It is not cheating. This isn't to hate on anyone who does think so but you're an idiot if you think so, let's take an example.
And Stay Down! - Win 50 matches of Elimination. Now, where in that trophy does it say you have to do it with public players? That's right, it doesn't. It just says you need to win 50 matches of Elimination. It doesn't say you can't do all 50 with your friends, now does it? No, it does not. So it is not cheating, cheating would be to hack your wins as you don't actually win as it says you need to 'Win 60 matches of Elimination' It does not say you must do it with public players, meaning boosting should be allowed.
So take that example those who think otherwise as none of the trophies say they must be done playing publicly without any friends to help you boost. If they did, it would be cheating, but it doesn't, so it isn't.
Personally there's nothing we can do to change this, but there's my view if anyone is interested.
