You would think anyone even at 31 had been relic holder, but some have never been in the raid at all. It took me around 10 Atheon sessions to take my first relic, purely because there was always someone in there with me who had done it before. One time I decided I needed to learn, so I just grabbed it. Best way. Fact is that, in your team of 6, you can afford a max of 2 players who don't want the relic. Any more than that and you're asking for wipes. Best way is to just grab it and learn. People won't kick off at you for doing it and dying (well they shouldn't) but might be unhappy if nobody picks it up at all.
