Okay, I am sure this has been brought up before, and somewhat thoroughly trounced, but I think that it's more important for longevity than some people seem to think it is.
Basically, while there are "many" ways to play the current Demigods, the selection is woefully small.
As an example, a Rook player who focuses on Towers of Light, and on his own add-on defenses will seem more similar to another Rook player who has focused on his Hammer Slam, than they would if they were both built from different chassis. And oddly, as the game progresses, the similarity between the 2 Rooks only grows, since at some point before level 25 they will start spending points on the same skills, while the 2 seperate Demigods would of course be completely different.
I am not suggesting that the current ability sets be broken up and attributed to other Demigods, that is just silly, and is a lot of work for the amount of return.
What I -am- suggesting, is that I will be sad if we finish up Beta without at least a clear promise that #1 priority is adding more Demigods to the game.
So, I thought that this could be a fun thread for discussing potential new Demigods, and the flavor and role that they would be best suited for, in order to provide inspiration to the Devs, so that they can see how exciting it would be to implement even more choices, and how many options there are available to them, once the game itself works great, and there is nothing to do but add content (of course Maps are important to our diet as well!).
Also, I cannot find this in the FAQ, but the game will have more flavor if the Demigods are segregated between Good/Evil. Of course to implement this now would not only leave the teams horridly imbalanced (only one side gets tank, sniper, mage, or melee artist), but Demigod selection would seem even more sparse than it does with 8 choices.
My first contribution - And I'll take an easy one. It's hard to imagine a game like this, without a proper rogue-like character. Someone who can stealth around and do dirty backstabby things. I know Erebus can become invisible, but he's a General, right? Just silly. I'm picturing a very fragile Demigod, who can fly. This would be a Good Demigod, and I'm seeing a Fae creature of some sort. They are not as brutally physically powerful as you mostly imagine a Rogue to be, they are more your Spec Ops character, with skills that do such things as increase the rate of Flag Capture, perhaps a DoT with a debuff, and perhaps a spell that dissolves a single Minion from Stealth, as well as personal Haste spell - their point is not to do an enormous backstab to destroy a low HP char, but rather to see someone in trouble and jump on them, blades flying in a frenzy of Evil slaying.
Obviously, with the skillsets that Demigod is using, less playable characters are needed to give a wide variety, than is the case in similar games (or "maps", shush about DOTA already). Each side having 8 unique Demigods would go a long way to providing long-term variety and enjoyment of the game - I have a hard time imagining anyone denying that assertion - it's just a matter of what kind of priority it is, and it's up to the beta players and fans to raise the priority in the eyes of the almighty.
