I think it's great that there's a sort of evolution. I can't picture (in a Star Wars galaxy sort of sense) the clone helmets just going straight from Phase I to Phase II.
Well yeah, but II is already an intermediary stage between I and the OT. How many additional "missing links" do we need?
What's Neyo's helmet supposed to be then, if PHase 1 is AOTC style, and Phase 2 is ROTS style?
Neyo's is way out there... Then there's the Marine's uniforms. The "Scout" armor from Kashyyyk...
I think the armor's a constantly evolving thing in the war, ultimately. New stuff developed for new reasons. Some legions in the outer rim could be fighting up till the end in the Phase 1 simply because they don't get resupplied as fast or often. You never know, ya know?
I'm all for specialization/customization, but it's getting to a point where a lot of new guys like the flamethrower trooper
look nothing like a clone trooper at all, in color or design.
There's meant to be a core iconic look for the Republic Army, and you can't tell me that the average Joe on the street (in-universe or out of, for that matter) would know that that's supposed to be a clone trooper without being told.
