Some drops just too rare?

[The Cid]

i play 4 to 6 hours a week and manage to get bronze arrows, fur, scale, lead and water. you must play with loot magnets like Winter

I have noticed since 0.5.0 patch, group drops seem to have tightened up.  Yet playing solo, seems to be a lot more generous, but I am still not getting any drops of water of h either way for some reason.
