My experience grouping in My Little Panda Adventure Isle is that the party forms, everyone runs around the area with no organization whatsoever and pulls whatever they want. Players constantly die and res, but somehow everyone continues to get rep and loot. It's like running a heroic with a go-go-go tank except you're not forced to endure the entire run to collect any meaningful rewards. I guess that's fun for some people. I personally think it's boring and pointless. Mostly I ride around tagging rares while waiting in my LFR queue and collecting my loot when the zerg overwhelms them. It beats sitting in the city losing brain cells on trade chat, but just barely.
