I'm actually not much of a shipper, and when I do ship half the time it's in a love/hate, too embarrassed to admit to it, way, but here are some of my main Tales ships, I guess >n> Feel free to share some of your own! Or if you're curious about another series, you can mention it! The main stuff I'm uncomfortable with is anything that involves a power difference. Like anything with an adult/minor (this might be defined a bit differently by the game's standards.) Put another way, I'm a really vanilla shipper. Ships involving childhood friends are my weakness.
For the older games, I'll probably have to replay them to get a better idea of what I like, but here's what I do remember!
I'm not really big on any Legendia ships.
Maybe Senel/Stella, Senel/Chloe, Shirley/Fenimore
Anise/Ion is the only one I'm really sure of whoops
Hubert/Pascal is kind of cute. I wasn't really into any Graces ships either
Alvin/Presa, Leia/Agria, Ludger/F.Milla, Rowen/Marcia, I've got mixed feelings on most Xillia stuff.
Sorey/Mikleo, Zaveid/Lailah, the two nameless seraphim that Heldalf RUINED
