Romford runs. Not the most efficient way, but certainly one of the safest ways.
what you could try doing is killing the first to wretched mothers, Going back to town, log out, then set to T6 and kill start the game again. Kite the 1st Wretched mother into town for some nice XP.
Hmm this doesn't feel right, first off I am killing all wretched mothers on T6 so why would I swap difficulties? Also kitting a mob back to town seems to be a long and tedious job.
I might be misunderstanding what you mean?
So far the only thing faster that I have seen is farming Matheal which is probably twice as fast but atleast 20 times more dangerous on Hardcore, also rumford gives alot of gold around lvl 60+ on T6 for the one giving the boost.
This method requires the one getting boosted to have atleast one lvl 60 however it is a really fast way to boost.
