Q: What race is best for Dragonknight?

Recommended races for Dragonknight, taken from my Dragonknight guide:

Orcs, Nords and Redguards best classes for tanks. High Elves are the most common race choice for mage-oriented Dragonknight players, but Bretons and Dark Elves are equally good for the role. If your focus is on melee DPS, Khajiit and Redguards are top two choices. Choosing a race doesn’t heave a very significant effect on your play style so players tend to choose whatever race they like playing, which is probably what you should do as well. Nevertheless, you can view our racial bonus comparison here.

In essence it depends on your build. Dragonknights do make the best DPS class in the game in highest endgame content, so you shouldn’t discount races just for their magicka bonuses. In fact every DK build will need plenty of Magicka to use numerous useful class spells, so if you’re completely undecided on your role and playstyle or just want to switch around often a Breton would be my top choice.

For melee DPS, Redguard or Imperial would be ideal as they make great tanks as well (most dungeon groups are looking for tanks, so it’s the easiest way to get into them).
