Same thing happened with the LFG I was with yesterday. The only difference is that we were in there unnecessarily for more than three hours. I hate when people say that they know what to do, but only on that spot are they actually learning the mechanics. Vault of Glass is my favorite raid from Destiny. In Destiny 2, I might classify it as my least favorite... only because the majority of players out there are dunces when it comes to executing simple raid mechanics.
