I've been experimenting with online play the past hour or so. For the most part does not seem any better than before with GFWL, sadly.
Seemed to work one time for me, when I tried the suggestion to change Steam's D/L region to Finland. Jumped in game and warped to Oolacile Township and right away my SL118 got invaded. Then for the next few minutes there were bloodstains and ghosts all around the bonfire there. I was thinking, all right seems like this is how to do it.
So then I quit out to load my back up save for my Darkmoon Blade character, jump in game again to the same place and its completely desolate. No bloodstains, no invasions, and my blue orb fails to invade time after time.
Its almost seemed as if briefly I was connected to a popular server, then just disconnected and could not rejoin.
