Low levels are fairly 'safe' now (no wandering Goobue near Bearded Rock, no Peiste around Blackbrush etc) but after r20 or so it picks up for sure.

Puks in Nanawa can be risky with smaller groups when Willowykes start respawning, sometimes two at a time in the same spot. The Amaljaa camp for the mid 20's wedges you between rank ~50s and rank 88 basilisks and drakes... There are also quite a few quests that send you through some 'dangerous' locations. Ahldskyf's second quest has you dodging r40 toads if you do it 'at rank', and Customer Comes First sends you into Cassie Holow where you have to dodge exploding Hares, aggro Orobons and if you're unlucky, the Unknown Soldier.

Granted, being r50 can nullify a lot that danger, your mileage may vary. A lot of deaths I've seen in groups come from people being half-aware when a willowykes starts beating on them or they don't move when a monster starts charging it's WS for a few seconds (i.e. Puks).
