You have some points, although I feel your characterization of the current mess with Will Peartree is a bit unfair - everyone will have a chance to get the nifty new festival horse - just a bit later than anticipated.
The removal of Will to avoid damage to the in-game economy (yes, there are still those of us for whom 10+ gold is a large amount of gold - and I'd hazard a guess that it's still a large majority of the player base to boot) was a swift reaction - driven in large part, I'd guess, by past experience with such issues where they did NOT remove it and then had to deal with the repercussions to the in-game economy.
It's interesting to see someone else's take on the same events and come up with such a different interpretation of what's going on.
The spring horse is just an example. It's more about the collected big picture of issues. I'm not super upset about having to wait for the new horse. In fact, (and I may be inviting bags of flaming poo on my doorstep with this one) I'm one of the people who actually reported the bug. Although, I did tell them that I'd be ok if they left the price at 3s
As to the economy, I definitely understand. 10 gold is a ton for me too. I think I have about 25 total, across all 9 characters.
