Thing is, when Fuhrer Bradley was introduced as Pride in 2003, it seemed wrong, because he was so... wrathful. I'm not saying that the version of Wrath they had wasn't wrathful, but for a personification of Pride, well, Bradley just was more angry than full of himself.
Honestly I thought Wrath in FMA would have fit as Envy better than Wrath. He was super jealous of Edward through the series, and it showed a lot more in his personality. Besides, Wrath in FMA:B definitely fit the part.
