It looks tedious, but if you buy a MQ it will cost you like 20k. Then like 90mins of skilling to get your Blacksmith to 160. Hardest part is to convince 2 groups of friends/guildies to come kill the the dragons. And lastly you hope you dont fail the last combine (should at 5% fail rate at 160 BS). But overall thats the best earring outside raids (if you dont call it a raid I suppose).
