When I read it I don't see it as arrogance. More likely he is just a very experienced player who has taken the time to understand the game and has practiced a lot. Expressing it on a strategy forum where a lot of other experienced players have the same level of expertise is different then if he was on TV or something.
If Michael Jordan was at the basketball hall of fame talking with Larry Bird, Kobe, Magic, etc and saying how dunking is just ridiculously easy I wouldn't take offense. I can barely dunk but I am not MJ. I don't have the practice and training hours he does and further I just don't have the genetics. Maybe it would be rude if he was addressing me but not if he is talking to Bird.
Most of us in this thread or those that frequently post in the strategy forum have played a lot and beaten Deity. He is talking to his contemporaries who have all accomplished the same goal via a lot of practice and studying of the game. My guess is it wasn't a post of arrogance but one that makes fun of the current lack of AI and game brokenness.
