it's just another label for various personality traits, like team captain, or cancer.. it's probably wiser to focus on the positive traits like work ethic or intelligence as just 2 examples, than worry about the label or missing a 'type' of player.. if they've made it more sophisticated than just the net effect on team chemistry / morale, i haven't read about that. (when they say 'drop in the bucket' description of morale -> net effect positive or negative when it's all accounted for per smallest increment of time that they update it)

i'm not saying there aren't specific benefits that certain types can provide, but it's due to the traits that make them that label, not hte other way around. so, if a sparkplug is encompassed by other types, you really do have a sparkplug, but a 'better' one too. (assumes this would have to be encompassed by somethign positive for obvious reasons) ... e.g. a team captain is a fan fav, or meets those qualifications, too. (total guess but i'm sure the situations exists)

as far as type:
something along the lines of a fan fav.. i was dinking around with some personalities the other day. a sparkplug turned into a fan fav after i increased a few thigns - unfortunately i was not paying enough attention.

high desire for winnign i'm sure - but do not recall what he was. although that was not something i improved... i can't recall if i bumped work ethic or intelligence..

if personality is one of the things we can filter, it will be easy to pick them out. even if it's visible as a 'view' with no filters, at least you can sort alphabetically and find it easily enough. not sure if that's possible
