To say this is a DF problem is a joke. I joined a pug for titan to get my 3rd relic since FC members weren't available, and because I had to keep an eye on my son while playing, I had some trouble avoiding titan AoE where I usually don't. I explained this to party members after 2 wipes and apologized, one member proceeds to tell me to "stfu" and they'll kick me if I mess up again. Didn't bother me really, but my point is, its not a DF problem, and its not possible to always do stuff with an FC, which makes it inevitable that you will run across these players.
