It's possible to resist the forced grouping and solo most of the ARR group content on the first character though. With exp buff and some fates to get ahead of the MSQ, the only 4-man dungeons i ended up not soloing were ifrit and titan. It was suprisingly easy too, with trash mobs usually being harder than most bosses. A bit weird that i switched to conjurer to get faster dungeon queues after finding out i'll need to do them to progress, but ended up not needing other people because i alone had enough dps/tankiness to clear pretty much everything.
