All of my characters were dwarves before I started doing PvP full time. The racial abilities are grossly outshined by Human stun trinket and for melee gnomish escape artist.
Other than that I love the dwarves, I love the lore, I love the starting zone, I love the animations and art. Once active racials are retired into a system where you just pick what you want to use like a talent, my characters will mostly go back to dwarf.
