Elves Attack!

[mailedbypostman1]

Except for one important element of this coalition, the Noldorin Eldar. They have a long and bloody history of underestimating their opponents, being attacked when unprepared, getting the tactical timing wrong, desperate last stands, and even a preemptive war when they only had a slender advantage. The frequent warfare culled their own numbers to the point of all the Noldor you see in LotR being wise, distant entities -- because the arrogant, rash, impetuous ones have all been killed.

True.

Which just makes them great cannon fodder and a distraction for the real elves.

Even with how this Rumble is set up, I can't see this one part of your post working out. ^_^

Heck, again on the Kurse thing, if he and Malekith are expected to be working together, this coalition could be a bundle of fun.

Both really more Gnomes despite their names.

Probably a PR thing. Gnomes are a readily exploitable source of cheap manual labour, but no-one would want to buy toys or cookies off the grubby little bastards.

Not really. They were just the popular image of elves before Tolkien.
