Thanks for advice. However, you should know that I did almost all my raids and nightfalls with guys I found on LFG (except for 2-3 raids which I did with a streamer who helped viewers doing raids). And I had bad experiences also. So, I already overuse LFG, but still cannot find people to play more than once (there are a few exceptions, but the general rule seems to be that you play only 1 game with people you find on LFG).
