I think we can go with our friends and do what we like, they will tolerate it or not. If someone joins with many unknwon people, he has to try his best. Do fates to spiritbond, do dungeons with your friends in underwear or snow suits, etc. for fun or achievement. There's no justification to not do your best for others. Some spiritbond if you are very overgeared and skilled may pass. Or in low level dungeons if you are well geared experienced.
