Felt I should return to this thread, and this post in particular, as you made a great point here.
As have previously said, I don't consider myself to be any good at the game. However, was discussing this with a friend a few weeks ago, partly bemoaning how much I love the QueensKnight weapons from 'Recollection' Ex and how disappointed I was that I'd never see my favorite of the bunch (the QueensKnight Syrinxi) on 'my' back.
After quite some persuasion said friend convinced me to join them, and a team of their friends (most of whom had already cleared it), to give Recollection Ex a try. And they made it clear that there wouldn't be any criticism if/when the team wiped and they'd simply explain what I did wrong and try again.
It admittedly took us three days to get the clear, partly because I was only able to spare a few hours each try) - but we did.
And I now have a weapon I thought I'd never own.
So I guess even a poorly-performing player like me can get it right so long as the right support is there!
