Of all the ways that Jellal could have come back, him saving everyone from Acnologia is the last thing I would have want to see.

Igneel's role after his come-back was small enough, but at least he managed to save everyone by driving Acnologia away at the cost of his life (or what remained of it). To take even that small triumph away from him and giving it to Jellal would have made Igneel's return entirely pointless to the story.
