Yeah Type 2 descriptions mostly describe ESEs, that's why. Most 2s are ESEs because there are more ESEs than EIEs, on average. (That's my interpretation of it at least.)
People use both + and - of their lead (and probably also demonstrative, aka the strongest functions). It can be situational, some EIEs might use +Fe more often around certain types that value it. I've seen myself using more -Ni around my SEE sis, for example. Though in my case it is also a bit more conscious to be fair.
You can argue for -Fe and 2 through the connection with Type 8.
