For all of you wanting to Face in 5e:
lvl 3: +disguise and Poison, + assassinate (if they haven't acted in a combat round you get sneak attack).
lvl 9: + 25 gp for a convincing backstory and the clothes and documents to back it up.
lvl 13: + mimic someone else real good
lvl 17: + death
lvl 3: Disguise and forgery kits, Master of tactics (help in combat at 30 ft)
lvl 9: Insightful manipulator: find out about NPC's
Lvl 13: Misdirection. Hit him not me.
lvl 17: Soul of deceit - no read my mind.
I think both stand a pretty good backbone for a face, I still lean toward assassin though, hitting the critical power at lvl 9 instead of lvl13 seems pretty awesome. If I could trade the lvl 17 powers, that would be awesome.
