I could see a lot of blind co-op'ing players want to take Lone Wolf, since it reduces party maintenance by quite a bit and being strangers it's going to take enough time and date planning to finish the game no matter what choices you make. I would think over time the GC option will fade some as you'll be playing with people with a couple play throughs completed and are looking for more of a challenge.
The good news is you'll now this right up-front at char creation, not many hours in.
