Dragon Knight.............so what 1/4 the player base are Dragonborn? Even if that wasn't their intention you are morphing your body with wings and spiky dragon armor so what the hell else do you assume it to be other than someone with a dragon soul.
Nightblade..............Come On! Seriously? I plan on making a NB caster and I will be using staves, not blades at all. Warlock or Death Mage would have been much better names.
Sorcerer............normally this would be fine but the definition of a sorcerer is someone who uses magic.........................EVERY CLASS USES MAGIC!
Templar...........by far the worst offender. This might not bother anyone who has never taken a European history class but what the [censored] does a religious order from early and medieval Europe have to do with anything on Nirn?
I get that they wanted to name them something other than the generic paladin, knight, rogue mage etc. especially since any class can play a tank or caster. But at least come up with some better names.
