Drangleic Castle is one of the best locations in any Souls game ever made. Kudos to From for that particular place. Currently trying to get my bearings on Undead Crypt.
It's funny, my SL is at 134 and I still get invaded and see a lot of co-op opportunites. I guess since the game is longer and people are still trying to find the best builds, PvP SLs won't be as low as the original Dark (sweet spot was at 80 if I recall correctly).
Also, 1000 Def+ against everything rocks
