Short version - it's not against the rules, but some Imms are less
inclined to seek interaction/rewards if they recognize reused roles.


Long(-er) version - It does depend on the Immortal, to a degree.
Overall, it definitely can't *help* you, if an Imm should recognize
it as "Oh, hell, I remember that from Newbdude the barbarian!". For
some Immortals, it can somewhat sour them against perhaps going above
and beyond for some extra fun. I can't really think of where it
would specifically detriment your character, however, aside from
possibly in the empowerment/religion aspect. In my personal case, I
can't even remember my kid's names straight half the time, so unless
it's the third time I've seen the same role on a shaman coming to me
for empowerment, you're probably in reasonable shape in my book. You
might run a bigger risk with some of the Imms who more heavily read
and rate roles.
