And in The Lord of the Rings, the Rivendell elves are among those who came from across the Sea. Galadriel is supposedly a descendant of that golden-haired one (or maybe not; hardcore Tolkien fans, please don't attack me! It's been a while since I read The Silmarillion!), and the elves of Mirkwood (or Twilight Forest or Black Forest) didn't even go across the Sea. That's why they are the weakest, and that's why Glorfindel chased the Black Riders relentlessly, while Legolas only once managed to hit one of those winged creatures.
Yes, and another thing about Tolkien and elves – they were very strong! And they even preferred melee combat to archery! In his works, besides Legolas and the elves of Lothlórien (well, and the people of Nargothrond, who, while hiding, shot passersby with poisoned arrows from cover), no one really used bows, but they eagerly engaged in melee combat.
Conclusion: Let's have elf swordsmen! Let's have elf swordsmen! And let their level not be the second one...
