Draupnir Cave

Hi everyone, I've heard 1 or 2 things and want to prove if it's right:

The Draupnir Cave's entrance seems to be working fine, at least it doesn't display the "You belong to a different race" message anymore, but I tried to enter (In group of 2) and I couldn't, so my question is, cannot enter at my current level anymore?? (I'm lvl. 55), or it's still bugged?

And a second question, I've heard that I can farm the same bosses of Draupnir Cave in Heiron, dunno if that is true, but wathever, my target is the ice black plate set or ebon shell plate set or elder plate set, so can I farm the ice black in heiron?, wich part would be?, there's any way to get the same armor model on an easier way? I'm Asmo lvl 55 by the way, anybody that reads it, please help, and thank you very much for your answers and time...Sorry Bad English...

I don't understand, many ppl have this set and they never wanna talk about where they got this...
