Howdy everyone! I'm a huge fan of the new Chaos Dwarf rules and models (as one could tell from my name) and I have read over the book countless times and have seen the use and potential of most of the units in the book and decided personally that they were good, bad, or amazing. Despite all my reading and pondering, however, I cannot make up my mind on K'daii fireborn. Their models look awesome and really have had me considering purchasing a squad of them, but I just haven't been able to fully convince myself that they are worth it in my army. What I ask of you, the warseer community, is what you believe their best squad size and application is if you like them, or if they just aren't worth it then why? So to start this off, I want to analyze a couple pros and cons and hope that this will spark a discussion that convinces me one way or another.
For the pros: These guys look like they would absolutely shred t3 models and do decent damage to t4 stuff. Their blazing body ability makes them difficult to kill and is what really makes them pound on weaker units, and at str 5 they can fight almost anything in the game and expect to do decent amounts of damage. A movement double that of the rest of my army is very handy too. The 4+ ward save on them is damn good as well. Plus they look awesome (but so does the rest of the army so thats not really a deciding factor).
For the cons: High points cost, 2 wounds and they potentially start to self-destruct after turn 1. They also have a low number of attacks for monstrous infantry. On top of all this, they essentially do what a very large portion of the CD army already does: Kill non-elite units. Things like the magma cannon, deathshrieker rocket launcher and hailshot blunderbusses all do the same thing very well, cheaper and better.
With this all said, what does everyone else think?
