Please supply a reference to the Elves of Mirkwood being frail. These same Elves followed Oropher and Thranduil into the War of the Last Alliance, and then later fought along with Celeborn's Lothlorien forces in the War of the Ring. By Tolkien's description, they seem well-equipped and fierce at the Battle of Five Armies. I would say the Dwarves were at a definite disadvantage in the open, and there are references to the fact they are much more dangerous in the close environment of their subterranean realms (where the bulk of the Dwarf and Orc War was fought).
