True, but you do know where the enemy will go after he has killed you: usually first to the base and then to the carrot, as long as you've hit him once. This is another advantage of CTF in the sense that the killer always knows generally in which area the victim will respawn (as long as, as you said, the start positions are sane) and the victim always knows where his killer will go. Because of this gameplay picks up quite fast after a kill whereas in most battle levels after a kill people can spend minutes looking for each other.
