I had my first go in a series of frag-limited Intermediate free-for-alls with a bunch of very polite Polish chaps, some (okay, one) of whom were actually worse than me. In that kind if game nobody minds a lollygagging newbie they can vape to increase their kills. I am absolutely awful at it, though - and me, completer of Quakes 1 and 2, Hexen, Dark Forces, various Dooms and Wollfensteins - but crucially all in single player campaign mode. Ah well.
