I know that Cataclysm is not out yet... But hey I'm kinda fed up with dragons since WOTLK...
So I've made some (possible story - including new Hero class)
First of all - why Demon Hunter? 0_o
Well from all the Hero classes ideas, the demon hunter is most resonable. Some people are coming up with such classes like arch-druid, arch-mage, shadow hunters... Well fair enough but you have to realize that (arch-druid is basically a druid with a title) same goes to arch-mage. Shadow hunters - well that's just a shammy with a little bit of Voodo twist. Blademasters are warrior/rogue hybrids. All sorts of Crusaders - will be equal to some warrior/paladin dude. While Demon hunter is something eintirely different... It has it's own Unique background, purpose and story which just asks for being developed even further, just like in the case of death knights.
Possible Story:
After the events of cataclysm (where we defeat DeathWing). Kil'Jeaden decides that it's about time to deal with Azeroth once and for all. Both factions will probably suffer alot after Cataclysm, Deathwing himself teared the world apart, the wars proved costly, some of the aspects will probably die, like cmon you know what I mean.
As Khadgar and all the Naarus play tick tack toe in outland. A freakin huge rain of fire destroys entire Shattrah City. The survivors decide to make Auchidon the new neutral City, transforming all of the previous instances into trade districts. Shattrah will become new raid/instance content zone. Survivors being aware of the upcoming invasion decide to send words to the faction leaders in order to send reinforcments.
New faction is born in order to prepare mortal races for the upcoming invasion. Hunters of Karabor (or something like that). Metzen just loves redemption stories (durning Blizzcon 2010 - Lore Panel) someone was asking if we ever going to see Illidan again). Well Illidan might be defeated but not killed. Maiev who imprisoned Illidan deep in the Karabor Sewers using all sort arcane techniques watches over (wicked, deaf, Nightelf Mongrel who is now a shell of his former self, Illidan remains silent as if he accepeted the failures of the past). Some starting zone quests might even involve passing by Illidan's prison as a warning to what might happen to young padawans if they do not obey the rules (the quest giver might be someone simillar to Instructor Razuvious). Kil'jaeden would make an apperance in order to convince the new formed faction to join his forces. And ofc we will need to help Akama and Maiev fight the traitors who now try to take over the Black Temple. Maiev leaves her best guards to keep an eye on Illidan.
We ofc repel the invasion and start in a new designed Hellfire Peninsula (new quests and plot)... We are ofc LvL 60
2 possible specs:
-something connected with demonology
-something connected with fel flames and stuff (just like frosty DKs)
Horde concept:
Alliance concept:
I realize that some Lore hero class combinations do not work... Like Draeneis and the whole power of light devotion. But hey If that can somehow repair or make their lore more interesting. Then I would give it a chance...
(There was alot of QQ about Tauren DKs - but in the end it worked out pretty well)
Keep in mind that it's just a Fan-Made post
Peace
