Eh, I've never been a fan of forced grouping mechanisms as social vehicles in games, so there's that. It's okay to be able to do a lot of basic things solo, or in DF.

That said, this game seriously lacks in flexible-size group content that's actually relevant. For the most part it's either 4 or 8 people or GTFO, and I'd like to see the game start to shift away from that a bit. Aquapolis is a good fun example of that, especially if the rewards keep being updated to be desirable. PotD is nice, but ideally you'll still want to go with 3 other people...I think mob scaling would do a lot to allow flexible group sizes to tackle it together.

So yeah. I don't want to be forced to group up for every little mundane thing, but it sucks not really being able to play with my friends in awkward group sizes like 5, 7, 10 people whatever.
