Drastic? No but two weapons don't need to be drastically differentiated from each other in order for there to be meaningful decisions between choosing one over the other. Just a slight difference in accuracy or range might make weapon A more favorable to weapon B but only in circumstance X as opposed to Y. There's [i]a lot [/i]of depth to be had when the player is allowed to fine-tune their loadout (and it gets away from having a single staple that you grind to death and never want to touch again, you're always tweaking, always shifting, which helps keep the game fresh without having to continuously develop a new game to replace the existing one.) Try counterstrike or rainbow six some time. They both demonstrate this principle very, very well.
