Welcome Hauggy
I'm part of the small group that loves Hyacinth to death too.
However, we've had a lot of feedback on it over the years and a good amount of it has been bad.
A while back 762 had a vote:

The majority of players on the server decided that they didn't like Hyacinth in it's current incarnation so the head admins decided to scrap it from the rotation until it's been updated. I kinda have to agree with them tho; Hyacinth, when it was in rotation, was just boycotted half the time it was on. People would stand at main and complain until the tickets ran out and a handful of people raced to the first objective just to get slaughtered by the whole Italian team.
I'm still for keeping Hyacinth out of rotation until it's updated, but that's mainly because I have the knowledge of what's been changed on it since 2.48
I'm pretty sure someone's already listed a few of the changes here before, but without saying too much, I think you'll enjoy our next update
