A simple knight is also a lot cheaper. By my estimates training a skill to 70% at an academy costs upwards 2,000 gold, so the requirement of training two skills to such heights as an infiltrator gives the class quite a hefty prerequisite fee, it's practically the cost of an army. Now you're telling me that they're visible and consequentially relegated to using their abilities only in unlikely or even contrived situations? That seems to make them completely not worthwhile, I for one won't be bothering with that class while this is the case.
