not sure if just bad players, but some ppl lack patience. do not use DF for speed runs...ppl say this a million times.
if soeone says their new...DONT RUSH it. or just leave :/
ppl must learn in this game: we are humans and we're bound to make mistakes.

i ran qarn, my fc mem and the brd was new, the tank hero rushed shxt and got insta killed by bees. i did was swift rez
and tried to use it. he died, clicked as fast as he could and left. the brd said he was new, but i had forgot to say to kill the bee's. [since i ran it may times.]
we were very lucky to get a very nice tank that explained the mechanics to them, and i helped out. a few wipes, but we had fun at the end
you must learn patience ppl. stop have the high expectations and assume folks know what to do right off the bat..
sometimes a few wipes are fun, you actually start communicating with your teammates and overall have a fun run at the end.
^^

sadly some ppl cant so they chew your ass out and insult you to the ground. this community is bad at times ...
