Thanks for the comments
So to pack some more punch I've got psycannons and fit all my dreads with a healthy twin-linked lascannon and missile launcher set up.
Now using brother captain with retinue, until I get more models and boost the army and then I can bring back the lord.
The reason my Brother Captain is still toting that Incinerator is just cause i'm a sucker for a good model. I'm going to use this guy with a Grey Knights paint job.
