I do! Of course, this is not important, but I still like II more than 2. It is a question of style. Dominions is more in the old than in the new, and II is older than 2. Well, I do not know any years, but II would have been used in the time Rome was the important nation. That is, before the cataclysm.
Besides, II is more exotic than 2. For me atleast.
