Let me start by saying I'm a casual player. If you're a hardcore fanatic and/or have a miniatures addiction then this probably won't apply to you. I really like what Wyrd did for the Ten Thunders. My local Malifaux group is made entirely of newbies and we all dragged each other into the game within a month. We have Arcanists, Guild, Ressers, Neverborn, Gremlins, Outcasts, and 10T, each one of us picking one (in a couple cases two) faction.
I only started playing around the end of the Wave 1 Beta test, but I believe there's solid principal for each faction, not just 10T. Each faction has its own flavor. Each one will appeal to different people for a variety of reasons. Within each faction there only really needs to be enough variety for those players drawn to it to find enough to suite their play styles. I believe Wyrd delivers and then some. Ten Thunders can quickly becoome a highly technical crew to run. It's also highly satisfying for those of us who do. (We can kill you with our minds.)
Wyrd seems to have balanced 2E well enough that everyone finds something. Is it the mostly kill-y crew ever? Probably not. Can I take on said kill-y crew with a personalized crew by playing to my strengths? Probably yes. There's synergy in the 10T and for those of us too stubborn to look elsewhere, we found it, are happy with it, and enjoy using it to prove Conan truly did know what is best in life.
