Mean Mm-Mm Servant of God
Personally, I would tend towards using attribute rolls liberally in order to give the scores more mechanical weight in the game than they explicitly have. But I wouldn't use ME rolls for resisting forceful personalities or anything because I don't think it fits: for instance, a lot of the faeries proper (faeries, sprites, night-elves, nymphs and so on) have low ME and I don't think that's because they're supposed to be easily swayed: I would guess it's because they're supposed to be flighty and not serious-minded.Ah, OK. Since people tend to say that it's still useful to roll stats even if everything below 16 is the same, because "you can use them as a guide for roleplaying", it's good to know what that means. (I have some issues with exactly that paragraph, but not many)
Thinking about it, 'serious-minded' might be a good way to think about what the ME score measures, except where it appears to just be shorthand for 'strong psi-resistance' (on which, see above).
