David Gemmel and Steven Erikson. Gemmel's work may not seem like masterpieces to you, but to many others he's as relevant as Moorcock and Leiber.
And Erikson...I don't know how the hell GRR is on tat last but Erikson is not. The Malazan series is more D&D relevant the anything in Westeros.
I did not mean to imply that I dont think Gemmels' work is good - I love them - I just thought they were a bit pulpy to be considered in the same type as Moorcock/Leiber/Tolkien (despite enjoying Gemmel more than those types of books)
