I like Fe. Although, I would just get rid of the T/F functions entirely- if it were up to me.
It's kind of weird having Fe secondary to Ni.
This is how the combination works for me:
I notice whenever patterns emerge and things change- Ni. I question if changes are necessary- Ni. To myself, I criticize people for being irrational or making bad decisions- Ni, Ti. I call them "stupid" in my head- Ti. But whenever I start interacting, I realize they're just people, not machines- Ni, Fe. So, now it's ok to be accepting and nice to them- Fe.
Fe works to soften the blow of Ni and Ti (NiFeTiSe). It also gives me a social life, because I can effectively participate in relationships (if I chose to be around people, that is

).
