Having had some fun with a ooze-centric UB build recently, I sometimes - during battle - end up suiciding when low on health; whereby the opposing team receives no gold. In the last game in which it happened, the other team resorted to the usual assortment of verbal assault, though I seriously doubt there's a study to prove that the homosexual demographic are more inclined to commit suicide (they didn't put it in so many words, but you get the drift).
I assume it would be fairer if a suicide was treated like any other kill - ie, the gold goes to the other team. I've only experienced suiciding with UB, though my experience with the other DGs is limited.
Lastly, to the people who consider it proper to verbally project all innate frustration at any player in the game: take a 10 minute break from the game, see if you can perhaps invent a new insult for your next outrage - and be creative, don't hold back on that vocabulary of yours. Surely an insult can be expanded beyond the 4-5 words employed today, no?
