Seen this a few times in swamp near destiny. Those fires are pretty handy for suicide noobs. Where's Jeffery when you need him?
Kidding aside, the major drawback I see in current implementation of suicide is the fact that they don't drop bombs or arrows. It's just an annoyance to have some random roll up on ya while writing a message and kill you for your ammo, then run off and kill themselves without any penalty. Damn punk thieves...
