Yeah, I'm really disappointed to have to remove origin again, but like I said we will hopefully have a map update soon to try and address some of the main problems without completely changing the map. To go a little more in depth, the map was playing too strong for both hunting and camping playstyles. Hunters could largely dominate the whole map with relative ease and keep zombies confined to whatever room they were in, and each room on top of that had anything from fairly strong to OP camping spots. The vast majority of rounds (at least that I viewed, obviously couldn't be there every time but I did watch it played a number of times throughout the month) had little zombie movement from room to room and many spots were difficult/impossible to conquer as long as enough CTs got there. The times when you were able to counter the hunters I'd imagine the remaining CT's were ones that stayed camping in strong locations like the pillar spot, so even with a sudden turning of the tides you're still left with a spot that is very hard to deal with. The main things we are going to likely update are adjusting a couple of the camping locations, and possibly adding some more areas for zombies to hide and ambush CTs so that hunting is a little more difficult.
Obviously everything we do isn't necessarily going to be liked by everyone, it's hard to please every single player when we have such a large community and each of those players is going to like and dislike different things, but we do our best to try and keep things fresh and overall give everyone the best experience on our servers. One day (hopefully soon) we will be looking at origin again.
