Just one of those things I've thought about since long ago but never shared until now.
How about adding incentives to players for completing queued content with less than a "full" party or queue group. For every character not included in the party/queue group, the loot table values increase which the best rewards (and possibly unique rewards, titles and/or achievements) only obtainable for solo completions.
Considering content played with less than a full party takes longer to complete or if it's even possible to complete, the reward and/or recognition should be equivalent.
And hardcore mode queued content successfully completed would correspondingly add another layer of reward providing the best loot.
