While I understand that this would be a maniac challenge, but since they have invented convenants we’ve been told basicly that they were ready to balance class specific covenants, and to treat them as class. (Which they’re clearly not.)
This is a possible concept of dual classing, and what it would mean for the game.
First, dual classing is there to add, not to remove. The point for me wouldn’t be to allow everyone to be whatever combo he wants just to add some intricacies with some new liberties, not all liberties. So I see it more as having 2 classes linked together, with or without a spec that could gather from each class. A spec that would often be something that the community have wanted in some form.
Mage + Priest
Prophet (dps hybrid)
Shaman+Druid
Earth Protector (tank hybrid)
Demon hunter + hunter
Fel Warden/Fel Hunter (ranged dps)
Death knight + warlock
Necromancer (ranged dps hybrid)
Rogue + Monk
Blademaster (melee dps)
Warrior + Paladin
Lord/Warlord (melee dps hybrid)
So each of those classes would have access to the other class in full way, and could have access to a new spec or an idea similar to what I’ve shown.
I could foresee this in the Lore as:
World of Warcraft : Legends of the Past
After having vanquished death itself, we have found out from what death was getting her power. From Azeroth old champions that got captured after their death. Their souls so powerful that it would make any realms tremble.
-Meet Grom Hellscream former Blademaster, ready to imbue the champions of Azeroth knowledge and training from his former days.
-Meet Cairne Blood Hoof former Earth Protector, ready to …
-Meet Cordanna Felsong former Warden that has fallen to the fel, ready to…
-Meet Kel’thuzad grandiose necromancer that never give up… ready to instruct…
-Meet Medivh that even death didn’t stop him from interfering with the mortal world of Azeroth but finally got caught. No one escape death. His power still exist and his ready to share it.
-Meet Anduin Lothar, champion of the Alliance and best sword that ever has existed. His hate for the fel is known and he has made it his specialty to fight agaisn’t it and to bolster his allies. He will train you.
This for me would be building up and amplifying the classes as we known.
*basicly the new specs would mix spells that looks like or are kinda the same from the classes it got blended. Also since it wouldn’t be a complete class added, it wouldn’t require as much development time (it would only be an additional spec). But yes this would still be an insane challenge.
