The old (and new) admins never really liked MH much or at all really. I think warp switched it for SH, but that was in like 2014 or so.
Obviously I preferred MH, and I mean I hate SH, but it's hard to tell what other people prefer. Its hard to figure out if the server back then with MH was popular for it or if it was just more people playing MTA, but MH was more about teamwork than SH, probably another reason why certain people wanted it taken down, same with CTF. The admins deleted Mower Rampage or Taxi Wars in CTF and said the above MH was ''buggy'', which was really just code for dislike of the gamemode itself, as they left the almighty CTF Cookie on... problem is without teamwork it becomes an arcade with each player in his own cubicle... and when there was a gamemode that literally consisted of blocking like CTF's mower rampage, when there was no ghost mode on NTS, and when people were cursing at each other on ManHunt, you can see that the rise of the Homo Adminus would cater to his own species and not take a liking to it all. I'm honestly not sure if the better votes SH has was manufactured and encouraged by those admins with the map deletions or if SH is genuinely popular.
