My guess is that the real reason was something to do with the Hasbro-mandated marketing for Shining Armour and Cadence.

That said, the Elements had already been used on Sombra once and had disembodied him, sealing him and the city away for 1,000 years. It could be argued that it would be a bad idea to use them again except as a last resort for fear it has the same effect again.
