This is probably my last thread on the topic.
I've got a power armor chaplain and a terminator chaplain, I've got a power armor librarian and two terminator librarians (one with storm shield, one with storm bolter), I've got a terminator captain, and I've got a model I could use as a Master of the Forge (without conversion beamer - I know I'll someday want both a MotF with conversion beamer and a MoTG with conversion beamer and bike). I've also got the start of a power armor (well, artificer armor, probably) captain - all he's missing is his head and arms... which brings me to the point.
Given how WYSIWYGlicious the captain's wargear is, and how many options there are, and the fact that I really only want to build one captain of each armor type, what do you think is the best loadout for a captain, with a special focus on the decisions that influence the way I build the model?
