Has anyone else noticed subtypes' effect on activity relations..?

Or any relations?

Ti-SLE and Ni-EIE is supposed to be an Activity relation; however, the subtypes make it feel almost like a dual relation.

Se-SLEs and I (Ni-EIE) get along really well usually... We rarely stop talking and laughing.

Ti-SLEs and I get along even better... They don't require as much effort to maintain the Fe, and thus I feel like I can be myself. (Not 100% like with a dual, but somewhere in the 90% range...)

The timing's slightly different than with a dual--and things that my dual would take in earnest, a Ti-SLE makes a joke of--but overall the relationship feels really close to duality.
