As it stands, I feel that shield boosting (AKA using the knight's shield up as a platform) is little more than a novelty function that has little purpose, and often in fact gets in the way when multiple knights attempt to wall-jump. Also, knights as they currently are are in most cases solitary creatures, who can get into a base and essentially hold it themselves if they can find a good position and are passably good. I think that since knight is a soldier class, this is not really a function which befits them (believe me I love doing this, but I just don't think it fits the flavour of the class). I think a way to solve both of these problems would be to remove infinite wall-jumping, and replace it with a buffed shield platform, perhaps it could function like a less powerful trampoline? Just an idea, and I think it would compliment the co-op flavor and the need for ingenuity in this game, as opposed to just buying two bombs which can get past anything or just infinite wall-jumping.
