I'm actually rather curious whether or not zDH + Condemn Crusader could replace zMonk + Firebats WD. Condemn isn't that far off from Firebats, when I compared them it was something like 14T peak DPS for Firebats and 12T peak DPS for Condemn.
Firebats has the advantage of considerably more Area Damage, but Condemn scales far better with damage increases from zDPS builds (as they're actually at -10% DIBS compared to +88% DIBS), and Condemn is able to create its own density meaning you don't need Cyclone Strike. Condemn is also able to reposition freely without losing DPS, Firebats is basically immobile by comparison with Endless Walk and Taeguk.
Edit: Area Damage is pretty broken though, and AD is really hard to fit into a Condemn build, so none of this may actually mater.
