Most people consider The One Ring BiS until you get the Dread Pirate ring. I however don't consider them BiS, but that's because my 10's have the GFd Ring of Scorn and I'll take the 3 stam over 1 agi/int/spr/str anyday. It's certainly a good ring now since Ring of Scorn and Minor Channeling Ring are no longer available and your only choices are the +1 int/spr, Dread Pirate Ring, The Horde Ghostlands wanted quest ring, and The One Ring at level 10.
