i'm imagining what if Summoner's Limit Breaks is they r summoning the real form of the primals instead of the same with meteor as the Black Mage has (which is not really Summoner's spell)??

Level 1 LB maybe able to summon Ifrit
Level 2 LB able to summon Garuda/Titan
Level 3 LB able to summon Garuda/Titan

but it must be little bit awkward when u fight Titan but u r summoning Titan too..

just in my dream, i guess..
