Or you could spend a little quality time reading learn about the elf gates.
Your point doesn't change the fact that the night elves, who have fought for thousands of years had to be lectured on how to fight and then had to be saved by humans. The only time the High/blood elves asked humans for help was when both parties were threatened. The first was to stop the trolls, who would have wiped both humans and elves out, the second time was Kael'thas wanting to help wipe out the scourge from Lordaeron.
