As someone pointed out in another thread, Guided Games is, contrary to the name, not a mode that is suppose to be sherpa/carry, but more like weighted matchmaking. They have X and they need Y, so they grab you.

But, like your post and likely most others have said, the only way for Bungie to really accomplish their goal is to have sherpa/carry teams helping other people. It sucks, but at the same time, this is a big reason why so many people were against matchmaking for the raid.

No offense to you or anyone else, but I don't personally expect anyone looking for the easiest way to get into a raid to be the best, nor do I expect the best sherpas to try their luck with whatever they get from matchmaking. So, what you often end up with, is lower tier players playing with one another and fail to do what is likely the easiest section of the whole raid (yes, the gauntlet is likely the easiest).

But, here is some food for thought. You took the time to come here and complain and wasted hours waiting/running with them, so what about dealing with this is better than LFG? How is the effort you put into this post more than it would take to find five other people? Etc.
