Hm. I'd suspect INTX enneagram 2's aren't as rare as we think. I don't correlate NT will lack of helper mentality, granted the fears of desire might have a different flavour to them than it would be of feeler.
Enneagram 8 for feelers is unusual, but that can be chalked down to extraversion. It'd make sense that these individuals might have a high amount of 1 within them. It's hard imagining an IXFJ enneagram 8, but I could imagine an IXFP who has adopted on enneagram 8 like values with Fi. Fi can be extremely diverse imo.
My enneagram fits with my type. Kinda normal tbh.
6w5 followed by (9/2/4/1) There's little 3/7/8 within me.
I'd like to think that most people will identify somewhat with enneagram 4, most people want to be unique and all that. But I guess it's a case of identifying that as your core self. My IXFP friend typed as a 4 (PS. Blackcat, it seems that there's a possability she was an ISFP after all. I was just being stupidly blind with the whole Se behaviour.)
