Right, we aren't focusing only on saber play. If anything we would just be making it a little more challenging by removing the ability to stock up on an arsenal of weapons before every mission, and rather find them in the level itself. It's not only about being "canon" because if it was, we'd eliminate gun pickup completely, which I don't think that would be fun or even realistic. Jedi would know how to improvise and be willing to. I think sometimes we view Obi-Wan's opinion of blasters in the movies as all Jedi's opinions of them, and that's not the case. But I don't think they would fill every nook and cranny with a weapon before going out on a mission that usually is just a "Hey Luke told us to check this situation out" sort of thing, rather than a full out army to army battle. In JK2 this is more understandable since he's a deadly mercenary, but for a Jedi padawan, probably not.
