Actually from what it seems, Sylvanas based on Be model and Alextraza based on Draenei model.

They've gotten better about that in general in WoW though. And as for the models, Sylvanas looks the part of a very powerful undead elf ranger that will kill you in a heartbeat if she decides you're an enemy. Alexstraza is much more powerful, but doesn't look it at all from that pic - a dragon aspect that's in the middle of stories including having to intervene to destroy a plague unleashed at Wrathgate, and to ultimately be the driving force behind the killing of another dragon aspect, should have a bit more purposeful look than that really... the fertility goddess people are referencing typically in mythology weren't the among the most powerful of the gods, certainly not in terms of brute force - Alexstraza could level entire armies, and is the leader of what currently appears to be the least fragmented and damaged of the 5 dragonflights. She should look regal and powerful, and she just doesn't... it's not so much the amount of skin, it's that she looks more like a slutty blood elf socialite more than a dragon aspect ><

I think a very applicable fix for that would be to give her a sort of resonating aura. You know, a visible, reddish aura, and maybe the ability to have flowers and grass sprout at her feet. It would really sort of reinforce her aspect and maybe also give that sense of power. (Birds should follow her around, imho)

Last I checked Ishtar and Kali were among the most powerful of gods. In fact, Ishtar is routinely referred to as the Sumerian Super Goddess and she plays quite a part in the epic Gilgamesh.

And hell, Kali was born to do what a man could not. One of the origin myths of Kali, she was created to destroy a demon niether man nor god (but not a goddess) could destroy.

Hera, Hathor, Freya, Serket, Artemis: all powerful Goddesses, though certainly some of them aren't Zeus or what not.

Portrayals of Kali, born a warrior, almost never has her armored.

In many game and book series, dragons are said to have no need for clothing or understand why mortals insist on wearing them. Warcraft is no different. Hell, its a game played by mostly male gamers. Even in the real world different cultures have different standards for dress and appearance.

Well, depending on climate, clothing can be very important. Dragons would have to be pretty dense to not see the utility of warm clothing in a wintery place for the hairless apes.

Beyond that, there's clothing for decoration, and considering Alextrasza's horn decorations I think she understands that just fine.

Just finishing up Zul'drak recently, it was nice to see the apperance of all the ZA bosses there and us "saving" them. Along with some other animal gods that play a role there. I would think Blizzard has a good setup there for another troll raid.

If you guys want to pick a bone about NPC's not seeming powerful, then lets start with Thrall looking extremely cartooney. His armor and weapons are true to Thrall, but they definitely could use an upgrade to make them look less shiny and Toys-R-Us like and more gritty and 'Hero of the Horde' like. I honestly hope all faction leaders are getting artwork reform: Sylvannas and Varimithas look positively awesome. Alexstrazsa as well.

Jaina's lvl 52 green quest gear also needs to go.

I'm pretty sure if it came down to something really important Alexstrasza doesn't have to worry about power and control being left to chance... you saw what Victor Nefarian did to Vael, right (or the orcish civilization comprising Blackrock Mountain/the Steppes) or what Onyxia did to a vast number of cultists/humans in her plots? Now imagine someone with power greater than their father.

The only entities Alexstrasza would have to influence on fair footing would be other Aspects, incredibly powerful cosmic forces like Elune or the Titans, or incredibly evil powers like Arthas or Kil'jaeden, and her ability to seduce would be irrelevant amongst them.

(and specifically taking high elven form is gonna have just as much effect making night elves and draenei naturally suspicious of her and orcs/trolls/taurens/dwarves/gnomes probably revolted by her as it gains in allowing seductive influence over humans and blood elves)

Perhaps a more apt solution would have Alexstrasza appear as the race of the player.
