With the recent race changes coming with Update 21, I want to gather other opinions from people who are very familiar with the Dragonknight Class, Magicka specifically, and see which class if now going to be considered “BiS” for The Magicka DK. Here are the current Magicka changes being implemented next update. If the changes to High Elf can stack with the Combustion passive then this will be extremely strong when it comes to sustain.

High Elf
Increases Experience gain in Destruction Staff Skill Line by 15%, extra 1% Generic Experience gain → No changes
Spellcharge: 9% Magicka Recovery → Spell Recharge: Restore 575 Magicka or Stamina, based on whichever is higher, after activating a Class Ability. This effect can occur once every 6 seconds. Reduces damage taken by 5% while you are using an ability with a cast or channel time.
Gift of Magnus: 10% Max Magicka → Syrabane’s Boon: Increases your Max Magicka by 2000.
Elemental Talent: 4% Fire/Shock/Ice damage → Increases your Spell Damage by 258.


Dark Elf
Increases Experience gain in Dual Wield Skill Line by 15%, reduces damage taken from Lava by 50% → No changes
Dynamic: 6% Max Stamina and Magicka → Increases your Max Stamina and Magicka by 1250.
Resist Flame: 3% Max Magicka and 2079 Flame Resistance → Increases your Max Health by 600 and your Flame Resistance by 2310. You are immune to the Burning status effect.
Destructive Ancestry: 7% Flame damage and 2% Frost/Shock Damage → Ruination: Increases your Weapon and Spell Damage by 258.


Breton
Increases Experience gain in Light Armor Skill Line by 15%, extra 1% Alliance Point gain → No changes
Gift of Magnus: 10% Max Magicka → Increases your Max Magicka by 2000.
Spell Resistance: 3960 Spell Resistance → Gain 2310 Spell Resistance and 100 Magicka Recovery.
Magicka Mastery: 3% Magicka Cost Reduction → Reduces the Magicka cost of your abilities by 7%.


In my opinion, it seems that High Elf would be the best choice considering how the are receiving a special bonus in when using a class ability they receive their main resource, in this case Magicka. I have not tested anything and these changes aren’t final until it is released on the main platform. Thank you for reading and I am interested in reading your opinions!
