If a group isn't managing to clear oracles I inspect each player. If any more than two people aren't using oracle disruptor primaries/praetorian foil/SGA I just leave. I don't want to waste an hour of my time getting frustrated. I play to have fun. You have the checkpoint now so start your own group on lfg. List that you want people 30+, confident with relic and using oracle disruptor primaries. Will take five minutes to build the group and then you'll beat it first shot. Much better.
