Summoner lore is consistent throughout Final Fantasy. Summoner's harness the power of the Summons to cause a combined Black Magic and White Magic Effect and call forth Summon Monsters. With their Summon Summoners have enough power to destroy an entire city. The problem is the Summoner doesn't feel very powerful while the Black Mage even though its not putting out insane damage still feels like a very powerful. In any given match up the Summoner will reduce the Black Mage to ash since Summoning Magic is stronger than Black Magic so why did SE make the Summoner feel weak in comparison to the Black Mage when Summoners are so much more powerful.
