Also asking for a whole new map rotation in general would basically mean scrap every map on the rotation and replace them; which wouldn't make any sense. If you only wanted Camel removed; why wouldn't you just say "please remove camel because X, Y and Z".
I understand your discontent with the map as I played it on ZPS before playing it on Gmod and didn't care for it when I played TTT; but I believe many of the others enjoy playing it. There are probably shittier maps than Camel that are on rotation too, but it's all a matter of opinion. Some maps are as entertaining as others but if there's nothing game breaking in it such as glitches or designs that make it unbalanced there's no real reason to remove it.
