Based on Atlasia Kingpoleon seems to always side with Labor, so my answer on that would be tilted "no"
Although honestly I don't know if anyone is a pure centrist. I'm not sure if that's possible, and it certainly isn't desirable. Computer is tilt right-of-center, Kingpoleon is tilt left-of-center.
"Moderate hero" is often used as a term mocking people who think centrism is a virtue, so I feel I should use this thread to point out that, while I am moderate-ish on several things myself, centrism isn't a good thing at all. I mean, it's not inherently bad, but it also isn't inherently good. (Oh crap I just accidently took a moderate hero position on centrism )
Moderate-ception. (buurrm)
I used to have a bad tendency to go centralist on a lot of topics, not because such things are bad, but because I realized I was just afraid to have an opinion, in fear that it might be wrong. Since then I've tried to actually take sides and have opinions.
