I do it occasionally with my brother.. I don't know if it is common though.
Although when I am looking for a group (Uw) as an SS (Not the 55/SS duo, just an Uw run), People constantly ask me to do it with them.. so Im guessing that people do it sometimes..
Thanks for the info. It is just that when I look on forums, most of the posts are "old" and I am unsure if they work. Given that it takes time, gold, etc, it is good to hear from ppl that are using a build currently that IS viable.
