Another thing I think we have to take in account is the lore behind the DGs. I've seen more than a few times here people wishing an egyptian demigod. If you read the lore well, you'll see that Unclean Beast is actually our Arabic Demigod at the moment.
I guess devs will continue to search for art/background ideas that completely differs from existing Demigod. I also think they are trying to put together Demigods that furthermore do not partain to any dichotomy that is culturally known (i wouldn't expect a classic horned-demon DG, it's too close to Reg), but instead really put a clash between completely different universes. Furthermore, I think the less bland-human DGs we have the better (i do like Sedna, though, but she's the human race representative, lets get something else). Someone said we need more Rooks ans QoTs, I agree, that's what made me buy the game.
So for now we have as background themes/"races" for our DGs:
Norsemen / Undead human - TB
Arabic / Demonic beast - UB
Woodland / Fairy - QoT
Vampire Lore / Vampire - obvious
Angelic / Fallen Angel - Reg
Your all-around medieval human village / Animated building - Rook
Inuit / Human - Sedna
Undefined noble exile (actually, I think that this kind of background that doesnt give details to exactly what kind of being a DG really spices up things, lets us imagine and opens up a lot of possibilities) - Oak
So what would be left for our next DGs? There's a still infinite potential, I hope the devs are really looking into it. Adding to that is the class-role model each Demigod has, which can totally differ from what the race announces. I mean it's normal to think of Rook as a tank, but seeing QoT; a fearie that is (supposed to be) the lead siege-engine of the DGs is another great idea.
Ideas - mine or other I've seen in the forums, but reformulated here (always in the background/"race"/class suggestion format):
More traditional :
Underground society / Small stature-race e.g. halfling / Thief-whatever well designed stealth mechanic
Savannah tribe / Pygmy / Hunter-type, hit and run tactics (give me a blowpipe skill please !!
)
Waterworld / Mermaid (why not make it an octopus-lady or crab-like man!) / Charm, creep control
More ecclectic (anything unusual, surprise us; that is what I long for) :
Magical accident in a sorcery-astronomy tower (said child of god fizzles a spell and soul gets embedded in things around him) / Animated contraption made of principally a telescope and other magical or laboratory-like furniture / Utility mage with observation, debuffs, mana drain, mana boost to team
Swamp (said child of god gets stuck is a hermit who gets so accustomed to his surroundings that he bcomes part of it) / Mud-swampish elemental / General with movement control and toads as minions
Oriental setting (said child of god is a servant in oriental court and falls in love with prince/princess and they become fusioned as a one and only being during a particular event, make it a war or cooking accident) / Androgynous human-like being with two sides, one male and one female / Lots of possibilities for class here
That'd be it for now, yours to comment
