Valens legions may have been anihallated at adrianople, but they fought well and bravely. It was Aetius, a roman general, who masterminded the extrodinary defeat of attila the hun at the catalaunian plains. And how did the Eastern empire manage to hand on for another millenium? The truth is that change and flexiblity were the army's greatest weapons, not it's weaknesses. Commanders had no problem with 'foreign' troops, weapons, ort tactics provided they improved performance."
That's how the spiculum came to be, and how it came to be replaced.
