Howrse
I play casually. However, my main focus is on Draft Shire Unicorns and a secondary focus on Marwari.
I am not really interested in buying horses, however if you have decent GP on a marwari foal or a Draft Shire Unicorn foal with over 4850GP and 2-3 covers left, I may consider purchasing. I will not purchase any with bonuses though, so don't offer.
As for other horses, I do not really focus on them. They are mainly for trophies and whatnot. I will work on them, but not as quickly as my main focus.
Unless it is for a daily objective I have to complete or have offered to help you complete, I will NOT offer coverings for horses that are not BLUP 100. This includes horses on both ends. If my horse is not finished with BLUP, please do not ask.
