Getting into certain factions

[fenix3279]

I just recently played a long campaign as one of the civilized factions and decided to take a small break from EB when I was done. A couple weeks later and I'm back on board the EB bandwagon. I decided to play as the Arverni again since it's been a while since I last played as a barbarian. I played the campaign for a few days but unexpectantly started losing interest. I'm afraid playing as the Romani for so long in my last game has somehow tarnished my view of the ancient Celts. My favorite EB factions have always been those of the ancient Celts but now I find it difficult to "get into" one of their campaigns. I actually caught myself referring to the Celts as uncivilized and smelly barbarians which I know is a stereotypical Roman and Hellenistic view. I was curious if this has ever happened to others. Has anyone else found it hard to get into a certain faction because maybe that faction was once your mortal enemy in another campaign?
