A community of people who mostly haven't attempted ltc arguing over whether Janaff or Soren contributes more in that setting is pretty stupid. As is one that spends months waging a community-splitting war over how to romanize FE12 character names. But those can't compare to what we have now, where a 4chan pastebin translation and a tumblr signal boost blog lead to an article in the third most visited business news site on the internet. I enjoyed following and talking to the guy who is trying to redo the fairly poor translations of FE 4 and 5, but he disabled his tumblr months ago in response to the constant FE14 flame wars that hadn't yet come near their peak.
The most unpleasant interaction I had in the pre-FE12 community was trying to explain the concept of variability to someone who had a really hard time grasping the PEMN meme and continued to post about how his level 15 Rebecca with 17 strength proved that she was better than Kent. Now I have to deal with people who haven't played a FE game regularly retweeting tharja porn on my timeline, and I'm pretty sure I got put on an anti-gamergate twitter blocklist for saying that I thought marriage, gay or otherwise, didn't belong in the new game.
