Looking to get that Tier 4 horse or Tier 6-8 horse of your dreams? I found a useful tool to help out with that. Though a lot of RNG is a factor when it comes to breeding this helps calculate the outcomes for you as a bit of a test.
They say a good formula is to start out with a Tier 1 female and get it to level 11 and breed it with a Tier 2 male at level 10 and you will most likely get a Tier 3 female. You can find many horses of different tiers on the Horse Market if you are willing to pay. Some are pretty cheap. Now if you get a Tier 3 male and a Tier 3 female to level 16 you can breed them for a good chance of a Tier 4. Get two Tier 4 to level 30 and you have a decent chance at a Tier 6.
