I agree, I only like the first armor too, the other armors covers up his face too much, the 3rd armor would have been much cooler if his visor was clear or only slightly tinted, but I am really REALLY glad that all the cut-scenes in ACIT have Ratchet with his helmet off. That was a really good idea.
But the armors in tools of destruction were much worse, I completed tools of destruction on normal and challenge mode without buying any armor because the armor all sucked. (and that meant it was a one hit kill from every enemy, but it was worth it)
I wish there was a skin in ACIT with Ratchet in his normal clothes from tools of destruction like in up your arsenal which had a skin of ratchet from the first one if you had a save file from the first one.
also I NEVER buy the final armors just for that reason that they cover his face.
