If summoning Tink, slapping on Aeroga, and randomly parrying attacks while button mashing is considered defensive :laughing-smiley-004
Plus I am an Ether whore. A ton of Ether allows Donald to heal more, Goofy to give more, and me to use a combination of spells and special moves more. It really cuts down on boss fights when you have an infinite amount of strike raids or arcanum moves. I definitely did those two moves the entire times to beat Sephiroth in KH1 (nothing else seemed to work)
