Ridiculous. If people want to be a stealth archer they can, but once you become over powered and legend up your skills, you naturally flow into more builds and skill learning, along with raising the difficulty to legend.
There is beyond space to grow and become the all round demi gorgon of Skyrim. By the end you should have dragons dropping onto prior archery, (dragonrend) then magic as they come closer aswell as no archer can sustain as well as the tank or mage builds.
