Developer Comment: Previously, Argonians were mathematically twice as good as some races. We wanted all races to stand out, yet still allow for choice of playstyle. Their focus is now on their natural healing capabilities, as well as their ability to prolong and stay in a fight. Now they have more stats in regards to what the goal of the race is, while they'll have less in other areas that weren't in line with that vision.
