Thing is that when there are multiple carrots and only one guy trying to keep you from collecting any of them, it takes a bad-as-hell mistake to get killed before you recover.

EDIT: Unless the carrots are very close to each other, in which case it defeats the whole purpose completely.

Also, never compare JE and semi. In JE the carrot is in the center of a wide, horizontal area and otherwise only accessible from below. This makes it easy as all hell to camp.
The carrot in semi, on the other hand, can be reached in a plethora of ways and the carrot is in a downhill area that can quite easily be attacked from the outside.
