I've seen a lot of people (and builds on Zam) that seem to favor a deep Marksman build (44) paired with the extra points in Assassin. I'm wondering why this is? I pair my MM build with Nightblade for the +15% builder/finisher damage (as well as Hellfire Blades + Melted Skin), and the nice thing there is that I don't waste any points in skills I won't use.
Is the Assassin thing just for the +crit/+crit damage and Lethal Poison? I had originally taken a pass on Assassin because I didn't like wasting 3 points in the second tier on skills I wouldn't need (Cloak and Dagger or Serrated Blades to get to the next tier), but maybe I'm missing something? Are the crit and bleed effects from Assassin better than the flat damage bonuses from NB?
My current build, for the curious: http://rift.zam.com/en/stc.html?t=0M...h.EMtRVzAudk.x. (I'll be going 10 Inf/12 NB when I hit rank 2.)
