I've found soloing in this game to be an enjoyable experience, I don't have to deal with certain sorts of folks, I get all the drops to myself and I can go at my own pace, I don't have to worry if I'm going too fast or too slow for everyone. I do seem to go quite a bit slower solo than in a group though, this doesn't bother me, as I'm in no rush to burn up my mist energy for the day.
My question though, is whether or not I end up with less money soloing than going through dungeons with a group. The wiki says that the money is the same, no matter the group size, though I must say, I've seen more gold coins dropping in groups than I see alone. Should I continue being a hermit or join the masses in my journeys into the clockworks?
Drops are random. Random is random. I wouldn't question that article's content, the part about the crowns was there from the start (i.e. first revision of the page) and it would be deleted if it was not true.
On the other hand, even if it was true, it would be a chump change difference in the crowns gain since i haven't noticed any significant change never and i've clocked like 12 days ingame time.
So yeah, don't let it get to you and just solo like you used to. Don't worry so much about crowns drops, since as you aleady know they are worth much less in comparison to materials.
