I just picked up an Ironclad Dreadnaught for my Black Templars army and am debating loadout. The intention is to use him in a drop pod and throw him down behind enemy lines to wreck havoc and try and divert fire from my other squads as they attempt to close on the enemy. I have yet to play with a dreadnaught in any of my games and have no idea which would best suit what I need.
I'm thinking that the chainfist will allow me to target enemy high AV mech and still be manageable in CC with infantry while the seismic hammer's biggest plus seems to be the ability to lower the opponents initiative which would enhance survivability and damage output in CC.
Any opinions or experiences?
