The ability to easily blow through ql180 and up missions or simply a fun group of people to hang out with? Ultimately, the ideal situation would be to have a combination of the two, but I find that RARELY happens. If you had to choose, which of the two do you prefer?
The reason I ask is, over the past couple of weeks of grouping with various people in BS, I've found I'd much rather have good, enjoyable company than being saddled with crybabies who blame everyone else when they die and generally take everything too seriously. In truth, I go to BS and team primarily to socialize and have fun, not rake in uber amounts of xp (though that's always nice). I don't care how many trips I make to the reclaim, I always have a good sense of humor about it, ya know?
