I tend to collect figures I like first, and then find a use for them later. 
I did that a lot when I had sufficient funds; these days I only buy models that I intend to use for a project right away (I actually ruled that I have to paint up a purchase before making a new one a rule that I have already broken on a small scale, but as the transgression consists of 6 small-scale spaceships for War Rocket that should not take me more than an afternoon to paint, I think I'll catch up).
I REALLY like that WM set. I could see multiple uses for it (actually, I have a Cygnar starter set that I never got painted, and the Jacks could come in handy for a variety of purposes, too).
I also have a lot of both large toy dinos (Schleich 1/48) and small metal ones (HLBS) that I should break out for some painting. So many minis, so little time...

(I have cardboard boxes bristling with minis for almost any setting/period out there - I'm not likely to ever run out of stuff to paint)
