I've been thinking about which Warmachine faction I'd like to try (currently I use Legion in Hordes). My son uses Cygnar, so my thought was that in the interest of maximizing bang for my buck, I'd pick a different faction than him, and eventually fill it out with some Mercs. If possible, I'd like to get Mercs that would, for the most part, also work for Cygnar so he could use them as well. And perhaps with the investment of a few caster models, I could also run a pure Merc army. So my questions are 1) does this sound workable? and 2) which Warmachine faction might be best suited for this? Currently, I'm leaning toward Cryx because I like the different look of the models and the background fluff (especially the dragon connection to Legion), but I'm open to considering others since neither of those are actual gameplay reasons.
