Problem definition : Sedna, Oak and Erebus will very rarely be used. I know a few disagree, but most agree, the reasons are obvious and I have heard no specific practical arguments from those who disagree.

In a 2v2 or 1v1 game, sure. Otherwise, no. I see all three of those a lot, and I use Sedna very often. In fact, I see QoT waaay less often than any of those three. So unless, you're anticipating some change, that just isn't true. I can't give you any practical arguments because I have no idea why you would think so.

Sedna, Oak, and Erebus are melee, have no serious ranged attack and relatively weak defenses ( compare for example : Paladin's Invulnerability is 15-30-45 sec, Heal is bigger than most attacks ). Empowering your team is not in itself attractive as a main goal for the average gamer, and even that is too weak as it stands.

Of course! They're not assassins! They're supposed to be geared toward the back line. If you want to improve them, improve that role. I certainly agree with the bit about empowering one's team, but that's because the average gamer is a ridiculously stupid.

Bite should easily be the most powerful attack in the game, being both melee-ranged and single-target ( same for Pounce ).

Ahahaha >.> Yeah, lets give give him an ability that pwns the hell out of any Demigod and heals himself to full. Again, hes not an Assassin. As for Pounce, it IS powerful. Damage aside, the interrupt effect alone makes it formidable. At max, it does 1100 damage, which is a very good chunk, and can be upgraded with a slow effect. The most powerful melee-ranged, single-target attack in the game is Hammer Slam, and its tempered by a slow character and a casting time. It even used to target Demigods instead of the ground, and the splash damage is really only for creeps.

Sedna has great melee survivability, and her heals are already good, they're just not going to make the enemy team completely impotent. With Healing Wind, Natural Grace, and Life's Child plus equipment, her regen can be really bloody insane. But again, it doesnt make her invincible, which is good.

Now, after raggin on ya so much, I have to say, I definitely agree that the Demigods should have more than one viable build. All we have right now are cookie-cutters of the same stuff over and over with one or two exceptions. I just think your presented ideas about going about it are wrong.

The 3 generals (except Erebrus) get stronger the more people there are on your team.  As mentioned, in a 1v1 match the 3 support generals do suck.  However, when you have +25% damage and -25% speed against a target for your whole team that is pretty huge when combined with any of the assassins.  Not to mention +20% movement and attack speed boost to your whole team means no one gets away from Oak.

Sedna obviously has the heals but she also has +20 health per second for the team along with -15% ability cooldown (great with Torch Bearer and Rook) and the very long silence can turn those big 4v4 battles into an easy win if timed well.

Queen of Thorns is more of a pusher/support rather than pure support like Oak and Sedna but with Uproot, Compost and Ground Spikes she can push towers faster than any other demigod (slightly slower than Rook against an undefended tower though).  For support she not only has a ranged 25% multi-target slow but she also has her shield which she can keep up on the whole team if they aren't getting attacked which means over 1000 health on each demigod going into a fight plus another 1000 health every 15 seconds.

All of the above listed abilities are not terribly useful when you don't have teammates to buff but with teammates they become extremely powerful.

What?

You're comparing General skills with Assassin skills and want them to be equally powerful. That's not gonna work. Erebus is actually incredible when played right - I've yet to loose against the supposedly overpowered Regulus for example.

Edit: And on Bite - a good Bite means a demigod kill. Buffing it would make Erebus the most overpowered Demigod yet.

Good job missing the point - even if the comparison was valid despite the genre difference (hint: it isn't), there'd still be no point of comparing them. There is no way SC2 will not outsell every other RTS/non-FPS. It will on the power of the Blizzard brand alone - there's no point in bringing it even up because it's success is 100% guaranteed irregardless of actual quality.

Plus, it's pretty easy not to understand what he was saying - it's gibberish.

The topic is quickly going off topic with SC2 talk, which is kinda pointless because its release date is unheard of. My bets are 2011.

Anyway, Sedna is far from being one of the weakest Demigods. Some of the best combos of Demigods in the game consist of her, and in a team match a good Sedna is your best friend. Erebus and Oak however are underpowered as you mentioned.

Like mentioned before, they are generals, and they do not have large spike damage moves as assasins do. However, I think Erebus's bite should be slightly more powerful (dealing maybe 200+ damage then it does later in the game, but not healing that extra 200.)

@sorry for the gibberish, english is not my mother tongue and i was probably really tired when i wrote that; because it is indeed gibberish...
Neverless, thank you for explaining my point: a comparison between Demigod and sc2 is pointless.

Back to the real subject, i also think that very often the minions seem totally ineffective and i usually dont use them.

But still,  1800 damages for bite! that attack heals the caster, it shouldn't  remove more than 1k hp. Moreover, I think that generals should rely on auras and group/aoe spells,  not on über-powerfull attacks.

SC2 is coming out at the end of this year (beginning of next year at the latest).  Beta is beginning most likely in a couple weeks. 

In any case, that's irrelevant.  He wasn't even being entirely serious, just trying to emphasize how right he felt he is by saying he'll buy somebody something. I just found the reactions to it amusing because people on this forum latch on to certain key words - "SC2" and "DotA" mainly - and run wild with them without really paying much attention to context.

And you are right : )

Maybe the fix I suggested is too much. maybe make the leech only half of the damage. I am quite convinced it has to be much stronger than Fireball though.

I think SupCom and even more FA are better RTS games than WC3, in several important aspects. StarCraft2 ( to set apart from SupCom2 ) does have to impress me with something.
