Continuing to update it as corrections are found and typos corrected.

Added suggested specializations and the pros and cons of each last night.

So, it's completely dependent on the fight.  In a short fight (read, soloing most mobs one at a time), yellow's going to do more DPS because it ramps up faster and is all about instant damage.  In a longer fight, red line will absolutely out-DPS yellow in comparable gear by a factor of 150% or more.  That said, the fast burn combo I listed will almost nullify this argument in most scenarios, as it turns red line into a burst DPS temporarily.

Edit:  I should also qualify that yellow has one huge advantage over red:  mobility.  If you have to run and/or kite the mob to survive the fight, you can do that in red, but only using yellow line abilities available to all RK's.

Aur, this is great.  Thanks for posting, helps out a budding RK quite a bit.  Do you feel that Red line is that much higher dps than Yellow?  I've been running yellow up to now (lvl 48), but am now thinking of switching it up.
