I often take long breaks from playing WO. Over the years I've always kept up at least one deed to house my horses, & whatever other critters I was into breeding at the time.
I went to such extremes as logging on alts to groom before breeding in a years long effort to not allow my mains AH to hit 60 because the old system was broken.
I have several alts I created solely to grind AH on so that they could care for all the breeding stock I wanted to keep. Now I have quite a few "clean" 5spd horses, in an array of colors, that I spent a lot of time & money on who have apparently been rendered virtually worthless overnight. I feel robbed of all the money I spent buying silver for upkeep & premium for AH alts. It was all for nothing thanks to this update.
When the fishing update dropped I hated it but out of respect for Tich I tried to keep my mouth shut. This is worse though because, as others have pointed out, while it's possible to simply avoid fishing it's NOT possible to play the game in any depth without this crap affecting you.
If I'd logged in today & been told that mules & draft traits were now a thing but in order to breed them I'd need to start out with wild horses & donkeys I'd be merrily galloping around the server hunting some of those rather than in a rage typing this. All AH needed was for higher skill to reduce the chance of getting negative traits. Draft traits? Great! Just not at the expense of making everything that's been done before useless. You need, at the very least, to somehow grandfather in animals that existed before the patch so they are not nerfed by the changes.
And since I'm on a rant can anyone give me one good reason why "speed" horses suddenly look like Arabians? Has Wurm been based in the middle east all this time & I never knew? It's an attractive model but it makes zero sense.
