Edit: Just thought I'd play around with the Daggermaster version with some different feats thrown around: Twin Strike: two attacks, vicious dagger: +15 to hit, 18-20 crit range, 1d4 + 9 damage (+3d12 + 1d10 + 1d6 fire damage on crit).
Hmm..
+15 to hit with 4+9 + 3d12+1d10+1d6 on a crit is not bad (18-65 on a crit)
but
I got
+15, 4+3, +3d6+24+1d10(maxed Sneak off of wraith blade on crit) which is 35-59 damage on a crit
The potential 6 more damage per round doesn't really offset the obscene minimum damage on a crit, and then at level 12 you can snag 2-weapon opening for more cheese
Also, didn't realize until just now you can retrain heroic feat slots to paragon feats! very cool
