What did this petting mechanic actually do for your units in the Japanese version?
Did it affect any stats? Affection level? Etc?
I'm curious about this too. It seems like a way to game the system, particularly with the Conquest version of the game preventing grinding and certain characters having their development progress differently during the game if their support level is high enough from what I've heard. Or are there still ways to raise support/affection levels outside of combat besides this?
EDIT: Looking over that sentence again it's sort of unintelligable. What I mean is that this was my impression of the game from what I've read about it.
1. The Conquest side of the game limits/prohibits grinding. Meaning that you have limited opportunity to raise support levels.
2. Some characters can have bad things happen to them if their support level with the Avatar isn't high enough.
3. The face rubbing minigame can raise support level outside of combat.
Are there alternatives to #3 so that I can prevent #2 in Conquest if I don't use that character enough?
