"the scipii looks cooler- but from what ive seen, the julii looks more realistic"

The Juilii hastati look more realistic - it looks odd to have chain mail sleeves atop a body that is only wearing a plate of armor over a tunic. The scipii hastati shouldn't have shoulder pads either.

The scipii principes look more realistic - they are clearly wearing a chain mail shirt. Juilii principes should have shoulder pads.

"It is just a different texture"

It's the exact same texture, just on one hastati/principe, the shoulder armor is alphaed out completely. In the other, it's not. They should be consistent.

"in normal view you will not see the difference at all"

I frequently zoom in on the fighting.

"I hope you agree that there are more pressing matters to take care of..."

I'm not a graphics guy, or I'd try to fix it myself :( All that might need changing is an alpha channel in photoshop or something. I think I'll go see if the TWC guys have anything on that - they are a mod crazy bunch to be sure :)
