ever since the original tie fighter came with one stormtrooper and Vader, everyone has been obsessed with creating an army of (insert name here). For me, I consider the # of figs in an army to be important. I have OCD and everything needs to have 2 or more friends. Like I have 3 AAT's, AT-TE's, etc. I also need to have ALOT of regulars (normal clones, B1's) as the majority and colored troops as the minority. I don't know what it is, but the brain tells you that a massive army is awe inspiring.
True lego is about building things, but it depends on what you want to build. For some it's BUILDING an army.
Customers shouldn't really complain about not enough figs. for example, hasbro has made the expensive AT-TE set with only one fig if i remember correctly. Well that's enough of my rant.
