Hi, I was just curious as to why people consider RIDs "difficult" to breed? I've seen a few people post in the forum on the topic and was just wondering!

Because RIDs can't be crossbred to produce an RID. RID can only be born of an RID x RID pair. In addition, they're not very well developed because the larger, successful stables have focused on ISH, SH, KNN, TB, and AA. The leaderboard studs aren't as strong in RID as they are in other breeds for the most part. They're also rather expensive.
