Not to discredit but can you be specific on rank please, I found hitting ranks for top 100 were easy and I could say, do it with any talent I chose (150 for bosses I was weak on) even subpar dps ones, but hitting top 20 required optimal talents and hitting top 10 required perfect play on top of that. Given shadowpriests are probably more common than enhancement just double the numbers (200, 40, 20)
