I should note that a blood talon dread radically out performs a furioso fist dread if you're also able to buff it via psyker powers, Dante, Tycho, or anything else.
As above, if you buff the fist dread in the same way, does it go back to being better than the talon dread?
There is a TLLC in the Dreadnought box. For Autocannons, it's a trip to FW.
Unless it's changed in the past few years, Dreadnought box is an assault cannon, TLLC, powerfist (SB & HF) and missile launcher.
Venerable box has a plasma cannon, powerfist and something else.
Doesn't one of them come with a multi melta option? I know the venerable box also comes with an assault cannon.
Normal dread - ass, las, fist, missile launcher
ven dread - ass, las, plas, fist
The AoBR dread came with a plastic multi melta, but that is now part of the "Battle for Vedros" starter set.
