Hmm, when you think of elves, the first thing that comes to mind is their excellent archery skills; axes and swords aren't really for them (since they are physically frail but fast).
this is because most people know nothing of elves, they use all these weapons and more such as swords for example, elves are quite strong and very powerful warriors, you see the Balrog in Lotr? Some elves could face them one to one and win like Gandalf did. Elves are a lot more than just archers
Actually, you've given me a few exciting ideas :D Maybe an elven horseman and an elven archer—or an elf with a spear and sword—could be placed in those empty slots you see on the screen.
