People like this are everywhere, it's simply unavoidable at some point or another. Maybe I've been lucky and have had maybe a handful of encounters similar to the situation you described, but again, it's unavoidable. What it comes down to is the fact that they shouldn't be expecting an instant win (or a win at all sometimes) when queuing up in the DF. The real "elites" are queuing up in the PF or with their own FCs and probably couldn't care less about DF. Individuals like the one you described are probably not as great as they think they are skill-wise, and certainly not pleasant to be around I'm sure. Just ignore them and move on, they aren't worth your time. :P
