Congrats
I started SP on SC with shared stash so it was kind of a different experience. It was a lot like b.net but without trading. I had dedicated chars for LK, Countess, Andy/Meph, and then the main chars which they supported which were basically CS/Baal mfers. I would xfer leveling gear to each new char and have their full gear waiting for them. It was all self-found, which was the first milestone for me, but it was a bit different.
Vanilla HC SC P8 is something entirely different, and far more rewarding. Congrats!
Enjoy all the new chars you will make and post em up for us!
