We all know that in a regular game of 40k, many FW units tend to be over-costed while under-performing. Not all, but still quite a few. For instance, I have never once seen any of the Space Marine-specific super-heavies on the table (ie. Fellblade, Falchion, Typhon, Thunderhawk, etc.). I know a couple players in my local meta do own them, but their points cost is just way too high for what they do.
That being said, I have seen the datasheets for a lot of the FW units for Apoc. And stat-wise, they don't seem half-bad. From my limited understanding it looks like just about every unit is worthwhile in some manner or another. I can't say they're balanced for their power levels, mostly because I just don't know. But on paper they look pretty good.
I'm curious, have any of you guys run any of your own FW models yet in an Apoc game? How did they perform compared to their 40k rules? I'd like to hear your thoughts and experiences on them.
