I think that some of it might just be a question of playstyle; some people prefer to always hit, whereas others (such as myself) feel that that makes rocket tag approaches too powerful and feel that if the attacker optimizes his attack to the same extent that the defender optimizes his defense then it should be around a 50% chance of missing.
