Aye, this is true. If the Dire Avengers and so on were super-slender that would be fine, but the Heavy Aspect Armour has to be bulkier than the regular stuff, or what's the point?

This is why Eldar doesn't join Slaanesh. The "she will eat ya soul" is just a cover up...

This is an old model if I recall. They used to be slimmer but now aren't.

Well thing is from what I could tell... Aren't SS supposed to be stealth units? As in not attract too much attention? To me it makes sense to have your stealth units a bit skinnier then your upfront infantry. Why? because good stealth doesn't require nearly as much muscle as infantry does.

Am I saying that the SS should be shrimps in the eldar army? No, but they shouldn't be bigger than the dire avengers.

*edit* Also get rid of this "all eldar must be thinner" idea we are already lighter than the (C)SM's and orks. in comparrison

As long as they have the stealth and shroud look. By that i mean more crouching than standing tall and long like guardians or dire avengers do:
