Big part of these discussions I feel is people trying to solo with suboptimal classes, builds, gear, pots, etc. Classic example is Slayer/Choppa solo queueing/roaming at low RR and gear, then complaining "why does this class suck so hard?" Ranged Dps seem to suffer much less from this affliction, can't even begin to imagine why.
Anger at deaths while soloing then inevitably becomes salt at the people who kill them, whom are inevitably people in a group, or superior soloers.
We are never gonna make everyone abandon the all solo all the time mentality. So to salve them salty wounds, perhaps lets share our builds and ideas for solo roam/queue as melee classes. Seen Volgo share pretty much everything about his build and set up, figure he is not only solo roamer/queuer enjoying success.
And who knows? Perhaps if someone is solo hero for long enough, they make friends and start grouping up? Can always dream, right?
