Imo, there are still some dangers... If you die at the waterfall fire giants, there is no chance you can save your things. You lose the ammy, making a trip back in 5 minutes impossible. Dying at Armadyl is also bad. Your partner would have to stand there for a VERY long time blessing your stone. 40 Armadyl kill count takes a while. I have 99 range, so don't argue that it doesn't take a while. So all in all, only really large boss battles are dangerous, as a 2 man team might not be able to save everything.
