Either remove them from the game or be transparent about their use. These are used as a gate for progression pure and simple. The "impact" of infusing is not fooling anyone as I think that vast majority of casual players or new players are feeling stunted by the mechanic rather than valuing it. To the people reading these posts, please remember that this is a developer who "solved" secret xp throttling by displaying proper values and DOUBLING the required xp. Those actions transparently communicate that they want you to grind needlessly. Such a shame because the base mechanics of this game are sublime.
