It has nothing to do with being accustomed to anything. Alot of us liked Dinklebot from the start and still do. I won't ever be able get accustomed to Northbot. He doesn't fit the part and I am pretty sure won't sound near as funny with that happy voice while chaos is going on the the dreadnaught.

Well, this is a matter of opinions. I personally think that Nolanbot gives cheerful attitude in to otherwise gloomy game. But as we say here in Finland "Makuasia sanoi kissa kun pallejaan nuoli." ( rough translation: A taste of things sayeth the cat while licking his balls."
