I choose NK's based more on who I think is able to lead town than about any other factor.
If I was scum I would have taken out pie. I want the scum team to lead the sheep to slaughter, not fool them.
Oromagi was widely town read. It could be an intended set up, but most scum teams like focusing on just eliminating the most town read players most and so I am not assuming it was a set up.
It's a bad set up if it was anyway. Oromagi could have literally found my address, showed up to my tent and punched me in my face, and that would not effect my actions in the game.
Even as scum, I don't pick targets based on how much I like or dislike them.
I also know it seems like I don't like oromagi, but it's a debate site. I don't really care how much I am called out or contradicted.
Oro.agi is definitely very odd in some regards if you pay attention. I don't dislike him. I like him. I like RM. I don't take these small spats seriously. I like you.
I don't like some users like Mikal or imabench, but it wouldn't effect how I play the game. I would interact differently, but NK reasoning stays the same. I'd probably just give reads and refuse to directly communicate with people I dislike. I don't dislike anyone in this game, even Oromagi.
It takes a lot to make me dislike somebody, and usually it has less to do with their actions towards me and more to do with what I know about their inner character.
